ZnCl2 Post‐Treatment Enables High‐Efficiency Violet CsPbCl3 Quantum Dot LEDs

open access: yesAdvanced Optical Materials, EarlyView.
Schematic illustration of ZnCl2 post‐treatment–induced doping in CsPbCl3 quantum dots (QDs). ABSTRACT Perovskite light‐emitting diodes (LEDs) have achieved external quantum efficiencies (EQEs) above 20% in the red, green, and blue spectral regions, yet their efficiency rapidly declines as the bandgap widens for shorter‐wavelength emission.

Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

Unraveling Mechanism of Photoluminescence in Hybrid Indium Halide Materials

open access: yesAdvanced Optical Materials, EarlyView.
Halide substitution in isolated [InHal6]3− octahedra reveals how bromide incorporation governs photoluminescence properties in hybrid indium halides. Ligand‐to‐metal charge transfer excitation followed by recombination produces a red‐shift and steadily increasing photoluminescence efficiency with increasing Br content.
