SIOM and Others Achieve Low-Threshold Red Single-Mode Lasing
Start here
The Shanghai Institute of Optics and Fine Mechanics, in collaboration with the Hangzhou Institute for Advanced Study, UCAS, made progress in low-threshold red halide perovskite single-mode lasers. The team introduced a PEATFA additive into CsPbBrI2 films, improving defects and carrier recombination through electron cloud redistribution and raising carrier lifetime from 2.38 ns to 7.12 ns. This ultimately enabled 660 nm red perovskite single-mode lasing in room-temperature air.
