Fabrication of amorphous phase encrusted oxynitride phosphor with white-light emission via in situ penetration†
Abstract
White-light emission is realized through assembling a blue-emitting amorphous phase on a yellow-emitting Ca-SiAlON: Eu2+ phosphor particle in the form of a coating. The variation of the yellowish–white–blue color is traced with the control of a blue-emitting coating formed via in situ penetration of
