Low‐Operating‐Voltage Yellow‐Green LEDs Based on Rationally Designed Copper‐Iodide Hybrid Clusters
The energy efficiency of conventional phosphor‐converted light‐emitting diodes (LEDs) is limited by thermal losses of light down‐conversion. This has driven interest in developing cost‐effective, phosphor‐free LEDs as a promising alternative for solid‐state lighting. Recently, copper‐iodide hybrid clusters exhibit cons...
