High-speed space optical communication based on metal halide perovskite single crystals

Abstract

In recent years, metal halide single crystals (SCs) have attracted increasing attention because of their excellent optical and electrical properties. In this paper, high-quality Cs4PbBr6 SCs were synthesized using a...

Stable and self-healing perovskite for high-speed underwater optical wireless communication

“…They find versatile applications such as light sources, wavelength converters, and photodetectors. 10–14 Notably, for green light emission, perovskite materials have achieved PLQY approaching 100%. 15,16 Perovskite green light-emitting diodes (LEDs) have achieved an impressive external quantum efficiency of up to 28.3% and a remarkable brightness, reaching 86 000 cdm −2 .…”
