Abstract Stabilization is one critical issue that needs to be improved for future application of colloidal quantum dot (QD)‐based light‐emitting diodes (QLEDs). This study reports highly efficient and stable QLEDs based on solution‐processsed, metal‐doped nickel oxide films as hole injection layer (HIL). Several kinds metal dopants (Li, Mg, Cu) are introduced improve the capability NiO films. The resulting device with Cu:NiO HIL exhibits superior performance compared state‐of‐the‐art...
ABSTRACT Light‐emitting transistors (LETs) as novel integrated optoelectronic devices demonstrate great potential applications in smart displays and visual intelligent perception. The construction of high‐performance area‐emission LETs with low power consumption good reliability is urgently needed for advancing their applications, however, this integration has not been realized within a single device. Herein, we kind planar‐driven hybrid LET (PDHLET) that makes use the unique advantages high...
Abstract Four crucifix‐shaped molecules, named TPA‐BPSB, DMAc‐BPSB, MTPA‐BPSB and MDMAc‐BPSB, bearing the same acceptor fragment of bis(phenylsulfonyl)benzene (BPSB) different donor segments (TPA MTPA are diphenylamine derivatives while DMAc MDMAc 9,9‐dimethylacridine derivatives) synthesized characterized by NMR, mass spectra, single crystal X‐ray crystallography. The molecular structure–property relationship these molecules is systematically explored. All compounds display thermally...
Organic solar cells (OSCs) based on chloroaluminum phthalocyanine (ClAlPc) as donor and fullerene C60 acceptor with a multi-tandem structure were fabricated. We demonstrated very high open-circuit voltage (VOC) enhanced power conversion efficiency (PCE) for the OSCs. Using fivefold structure, we obtained PCE of 2.49% VOC 3.50 V, in comparison ∼2% 0.72–0.81 V single device. also fabricated tenfold-stacked OSC showing an extremely 5.89 V. The OSCs have great potential applications limited-area...
We have demonstrated amplified spontaneous emission (ASE) characteristics of binary blends with green and red laser dyes ternary three primary color dyes. The results show that the stimulated rate donor can be balanced Förster resonance energy transfer from to acceptor by adjusting doping concentration or dye, leading realization multi-wavelength ASE. blend is at 493 570 nm threshold 15.7 19.1 μJ/cm2, respectively, while 452, 510, 596 22.0, 18.6, 23.8 respectively.
Continuous-wave (CW) and Q-switched operation at 1617 1645 nm in a resonantly pumped Er:YAG laser is reported. A U-shaped resonator incorporating an acousto-optic Q-switch was used, etalon employed to select the output. In CW yielded 3.68 W 4.01 nm; 2.09 mJ 750 Hz repetition rate 2.07 1 kHz nm.

Aluminum‐doped zinc oxide (AZO) has been regarded as a potential and promising material for thin‐film transistors (TFTs) owing to its low cost nontoxicity. Generally, the high conductivity of AZO should be suitably reduced before using in TFTs semiconductor. Traditional ways reduce is by increasing doping content aluminum (>5 at%). Herein, novel approach first reported convert conductive into semiconductor rationally designing bilayer channel structure that consists an island film thin Al...

This work shows a promising approach to improve device performance by optimizing the electron transport and hole injection layers for tetraphenyldibenzoperiflanthene (DBP):rubrene-based red fluorescent organic light-emitting diodes (OLEDs). We compared effect of two (ETLs), found that rubrene/bathophenanthroline (Bphen) ETL-based OLED showed much higher external quantum efficiency (EQE) (4.67%) than Alq3 (EQE 3.08%). The doping ratio DBP in rubrene was tuned from 1.0 wt% 4.5 wt%, 1.5...
ZrO2/zircone nanolaminate thin films fabricated by atomic layer deposition were used for a distributed Bragg reflector (DBR) in green organic light-emitting diodes (OLEDs). It is found that the novel DBR structure significantly improves light purity of OLEDs without interfering with intrinsic electroluminescence properties.
