Phellodendron chinense Schneid: A novel yellow-emitting luminescent material for white light-emitting diodes

Abstract To facilitate the next generation of environmental material for white light emitting diodes, the discovery of natural luminesce is essential. In this study, we disclose a rare-earth free and yellow-emission phosphor, Phellodendron, which could be both excited by near ultraviolet light and b...
