Temperature induced variable chromaticity lanthanide multidoped solid-state phosphors are presented. The phosphors are composed of ytterbium-sensitized multiple-doped (Tm, Er, Ho) PbGeO 3–PbF 2–CdF 2 glass excited at 1.064 µm. The temperature induced color variation exploits the heat enhanced effect...
