Single-particle spectroscopy of CsPbBr3 perovskite reveals the origin low electrolumine

Researchers have used the method of single-particle spectroscopy to study electroluminescence in light-emitting devices. They discovered that efficient charge funneling between individual perovskite nanocrystals and the phenomenon of emission blinking are responsible for the low efficiencies of perovskite light-emitting devices.
