Single-particle spectroscopy of CsPbBr3 perovskite reveals the origin low electrolumine
(PHYSorg.com Chemistry)

Researchers from Tokyo Institute of Technology (Tokyo Tech) used 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.
