The transition from vegetative to reproductive phases during Arabidopsis development is the result of a complex interaction environmental and endogenous factors. One key regulators this LEAFY (LFY), whose threshold levels activity are proposed mediate initiation flowers. closely related APETALA1 (AP1) CAULIFLOWER (CAL) meristem identity genes also important for flower initiation, in part because their roles upregulating LFY expression. We have found that mutations FRUITFULL (FUL) MADS-box...
Quasi-2D perovskites have long been considered to favorable "energy funnel/cascade" structures and excellent optical properties compared with their 3D counterparts. However, most quasi-2D perovskite light-emitting diodes (PeLEDs) exhibit high external quantum efficiency (EQE) but unsatisfactory operating stability due Auger recombination induced by current density. Herein, a synergetic dual-additive strategy is adopted prepare films low defect density environmental using 18-crown-6...
Highly efficient organic thermally activated delayed fluorescence (TADF) and room-temperature phosphorescence (RTP) emitters for light-emitting diodes (OLEDs) generally consist of a twisted donor-acceptor skeleton with aromatic amine donors. Herein, through introducing sulfur atoms into isomeric pentaphene pentacene frameworks, we demonstrate set polycyclic luminophores exhibiting TADF RTP characters. The incorporation confirms folded molecular plane, while intensifies singlet-triplet...
Purely organic room-temperature phosphorescence (RTP) materials generally exhibit low quantum yield (ϕP ) and long lifetime (τP due to the theoretically spin-forbidden triplet state. Herein, by introducing a donor-acceptor (D-A) skeleton with phenoxaselenine donor, three nonaromatic amine donor containing compounds high ϕP short τP in amorphous films are developed. Besides enhanced spin-orbit coupling (SOC) heavy-atom effect of selenium, D-A which facilitates orbital angular momentum change...
Immunotherapy and radiotherapy play crucial roles in the transformation therapy of locally advanced pancreatic cancer; however, exploration effective predictive biomarkers has been unsatisfactory. With rapid development radiomics, next-generation sequencing, machine learning, there is hope to identify that can predict efficacy transformative treatment for cancer through simple non-invasive clinical methods. Our study focuses on using computed tomography (CT), positron emission...
Solution-processed organic–inorganic lead halide perovskites have recently emerged as promising gain media for tunable semiconductor lasers. However, optically pumped continuous-wave lasing at room temperature, a prerequisite laser diode, has not been realized so far. Here, we report action in surface-emitting distributed feedback methylammonium iodide (MAPbI3) perovskite on silicon substrate temperature under optical pumping. This outstanding performance is achieved because of the ultralow...

The N‐GQDs have uniform size 3.06 ± 0.78 nm and prefer the equilibrium shapes circle ellipse due to minimization edge free energy. N / C atomic ratio in can be precisely tailored range from 8.3 at% 15.8 by simply controlling concentration source (ammonium hydroxide). One order magnitude yield 34.5% is achieved N‐GQDs, compared with N‐free...
Fast spin-flipping is the key to exploit triplet excitons in thermally activated delayed fluorescence based organic light-emitting diodes toward high efficiency, low efficiency roll-off and long operating lifetime. In common donor-acceptor type molecules, distribution of dihedral angles film state would have significant influence on photo-physical properties, which are usually neglected by researches. Herein, we find that excited lifetimes emitters subjected conformation distributions...

We propose an experimental procedure for testing the Einstein relation carrier drift and diffusion in semiconductors exhibiting non-Gaussian or dispersive transport. present corresponding hole time-of-flight steady-state photocarrier grating measurements hydrogenated amorphous silicon ( $a\ensuremath{-}\mathrm{S}\mathrm{i}:\mathrm{H}$). For a range of mobilities ${10}^{\ensuremath{-}5}--{10}^{\ensuremath{-}2}\mathrm{cm}{}^{2}/\mathrm{V}\mathrm{s}$ we find that our estimates are approximately...
Electrically driven subwavelength scale metallo-dielectric pedestal pillar lasers are designed and experimentally demonstrated. The cavity significantly enhances the quality factor (Q > 1500) of wavelength structure reduces threshold gain (< 400 cm(-1)) which can potentially enable laser operation at room temperature. We observed continuous wave lasing in 750 nm core radius temperatures between 77 K 140 with a current 50 μA (at K). also from 355 100 K.
The quest for an integrated light source that promises high energy efficiency and a fast modulation high-performance photonic circuits has led to the development of room-temperature telecom-wavelength nanoscale lasers with spontaneous emission factor β. coherence characterization this type laser using conventional measurement output intensity versus input pump is inherently difficult due diminishing kink in curve. We demonstrate transition from incoherent coherent high-β pulse-pump...
Perovskite light-emitting diodes (PeLEDs) have drawn considerable attention for their favorable optoelectronic properties. electrochemical cells (PeLECs)—devices that utilize mobile ions—have recently been reported but yet to reach the performance of best PeLEDs. We leveraged a poly(ethylene oxide) electrolyte and lithium salt in CsPbBr3 thin films produce PeLECs improved brightness efficiency. In particular, we found single-layer PeLEC from CsPbBr3:PEO:LiPF6 with 0.5 wt % LiPF6 produced...
Abstract Generally, the charge transfer character of thermally activated delayed fluorescence (TADF) materials results in a long excitonic lifetime and broad‐band emission. With combination unity exciton utilization TADF material high radiative rate narrow‐band emission conventional (CF) dopant, hyperfluorescence organic light‐emitting diodes (HF‐OLEDs) attract extensive attention industry academia recently. Till now, Dexter energy (DET) from triplet state assistant host to dark CF guest is...
Purely organic materials usually exhibit weak spin-orbital coupling (SOC) effect because of the lack noble heavy metals, and generation direct emission from triplet state is spin-forbidden. This would lead to slow intersystem crossing, long lifetime, low phosphorescence quantum yield. Herein, strong between singlet was observed in a "flexible" twist thianthrene-pyrimidine-based purely compound an amorphous film state, which shows fast crossing process high rate 1.1 × 103 s-1. The atom sulfur...
Abstract Quasi‐2D perovskites show great promise for light‐emitting diodes owing to suppressed non‐radiative losses enabled by the energy funneling/cascading nanostructures. However, red emission quasi‐2D perovskites, these ideal landscapes efficient perovskite (PeLEDs) can rarely be achieved due detrimental aggregation of low‐dimensional ligands in precursors, leading poor device efficiency and stability. Here, a ligand‐modulated dimensionality control strategy is explored achieve uniform...
Abstract Perovskite light‐emitting diodes (PeLEDs) are advancing because of their superior external quantum efficiencies (EQEs) and color purity. Still, additional work is needed for blue PeLEDs to achieve the same benchmarks as other visible colors. This study demonstrates an extremely efficient PeLED with a 488 nm peak emission, maximum luminance 8600 cd m −2 , EQE 12.2% by incorporating double‐sided ethane‐1,2‐diammonium bromide (EDBr 2 ) ligand salt along long‐chain methylphenylammonium...

We present a formal treatment of the modification spontaneous emission rate by cavity (Purcell effect) in sub-wavelength semiconductor lasers. To explicitly express assumptions upon which our formalism builds, we summarize results non-relativistic quantum electrodynamics (QED) and emitter-field-reservoir model theory damping. Within this model, emitter-field interaction is modified to extent that field mode its environment. show Purcell factor expressions frequently encountered literature...
