Abstract
Blue-emissive Cs<sub>3</sub>Cu<sub>2</sub>I<sub>5</sub> and yellow-emissive CsCu<sub>2</sub>I<sub>3</sub> microscale crystals were synthesized by a facile supersaturated recrystallization method at room temperature, and a stable WLED was demonstrated by using both materials as down-conversion phosphors.
