Perovskite quantum-dots are promising candidates for light-emitting diodes but the defects limit the device performance. Here Xu et al. show a passivation strategy to reduce the defect density at both interfaces, which increases the external quantum

Abstract Perovskite based light‐emitting diodes (PeLEDs) have become a powerful candidate for next‐generation solid‐state lightings and high‐definition displays due to their high photoluminescence quantum yield (PLQY), tunable emission wavele

Copper-based halide perovskites have been considered as promising scintillators. However, they still cannot meet the requirement of low-dose-rate X-ray imaging in medical diagnosis. Herein, we design a fiber optic plate (FOP) coupled perovskite X-ray

Here, we firstly propose an A-site engineering strategy to improve the luminescence performance of Cs3Cu2I5. Through the incorporation of FA+, the lattice defects in Cs3Cu2I5 can be reduced and the PLQY of the optimized sample is increased to 95%.

Anxiety and depression are common in functional dyspepsia (FD) patients. Although fissured tongue (FT) is often observed in FD, its clinical value in such patients is rarely reported. We analyzed clinical data of FD patients with FT with the aim of e

Voltage loading-induced change in the electroluminescence (EL) wavelength of mixed halide perovskite light-emitting diodes (PeLEDs), so-called color-shift, has become an inevitable phenomenon, which is seriously unfavorable to their applications in l
