Monolayer transition metal dichalcogenides (TMD) with confined 2D Wannier-Mott excitons are intriguing for the fundamental study of strong light-matter interactions and exploration exciton polaritons at high temperatures. However, research has been hindered because in these atomically thin semiconductors discovered so far can hardly support nonlinear quantum coherence due to uncontrollable polariton dynamics weakened coherent coupling. In this work, we demonstrate, first time, a precisely...
Closely aligned configuration of the donor (D) and acceptor (A) is crucial for light-emitting efficiency thermally activated delayed fluorescence (TADF) materials with through-space charge transfer (TSCT) characteristics. However, precisely controlling D-A distance blue TSCT-TADF emitters still challenging. Herein, an extra (D*) located on side primary introduced to construct hydrogen bonding A thus modulate D units prepare high-efficiency TSCT emitters. The obtained "V"-shaped emitter...
The condensation of half-light half-matter exciton polaritons in semiconductor optical cavities is a striking example macroscopic quantum coherence solid-state platform. Quantum possible only when there are strong interactions between the provided by their excitonic constituents. Rydberg excitons with high principal value exhibit dipole-dipole cold atoms. However, constituent that an excited state, namely (REPs), have not yet been experimentally observed. Here, we observe formation REPs...
Single photon emitters (SPEs) are critical building blocks needed for quantum science and technology. For practical applications, large-scale room-temperature solid-state platforms required. Color centers in layered hexagonal boron nitride (hBN) have recently been found to be ultra-bright stable SPEs at room temperature. Yet, scale up information processing, large tuning range of single energy is demanded wavelength division multiplexing key distribution, where indistinguishability not...
Microbially induced calcium carbonate precipitation (MICP) is an environmentally friendly technology that improves soil permeability resistance through biocementation. In this study, 2D microscopic analysis and 3D volume reconstruction were performed on river sand after 24 cycles of bio-treatment based stacked images computed tomography (CT) scanning data, respectively, to extract biocementation patterns between particles. Based the mutual validation findings two techniques, three in...

The biomimetic design of engineering structures is based on biological with excellent mechanical properties, which are the result billions years evolution. However, current structures, such as ordered lattice materials, still inferior to many biomaterials in terms structural complexity and properties. For example, structure ofEuplectella aspergillum, a type deep-sea glass sponge, an eye-catching source inspiration for design, researches have introduced similar architecture cellular solids....
A methyl-modification strategy is proposed to enhance the ICT and RISC processes of ultra-deep-blue through-space charge transfer emitters. The prepared emitter 3MeCz-BO achieves a high EQE max 10.1% with CIE coordinates (0.151, 0.051).
Metal halide perovskites have emerged as promising gain materials for on-chip lasers in photonic integrated circuits. For these to become commercially relevant economical light sources, a clear onset of quasi-continuous wave (quasi-CW) and, eventually, continuous (CW) lasing at room temperature or Peltier-cooling accessible temperatures from directly patterned perovskite cavities is critical milestone that must be achieved. Herein, through patterning with nanoimprint lithography and...
Exciton polaritons (EPs) are partial-light partial-matter quasiparticles in semiconductors demonstrating striking quantum phenomena such as Bose-Einstein condensation and single-photon nonlinearity. In these phenomena, the governing process is EP relaxation into ground states upon excitation, where various mechanisms extensively investigated with thermodynamic limits. However, becomes drastically different could significantly advance understanding of dynamics for when excited EPs involved....

Blue-emitting thermally activated delayed fluorescence (TADF) polymers are still in demand for high-efficiency display materials. Through-space charge transfer (TSCT) strategy is promising keeping color purity of blue-emitting with nonconjugated main chains. It is, however, hard to synthesize copolymers well-dispersed donors or acceptors utilizing traditional polyethylene backbones via radical polymerization. Herein, two series polysiloxane TADF properties, random and order-controlled...
