Glass Forming Ability and Luminescent Properties of P₂O₅-ZnO-SrO System Glasses

Abstract:

Glass-forming ability in the P₂O₅-ZnO-SrO-K₂O system was investigated using differential thermal analyzer (DTA). The results showed that adding appropriate amount of K₂O could improve the glass-forming ability of phosphate glasses. Meanwhile, the spectroscopic properties of Tm/Tb/Mn co-doped phosphate glasses were studied by photoluminescence (PL) measurements and CIE color coordinate. Blue, green, and reddish orange emission bands were observed in the PL spectra of the phosphate glasses. The combination of these emission bands gave white light by ultraviolet light excitation (360nm). As the Tb₄O₇ was increased,a gradual shift from white emission to yellow emission was observed in the PL spectra of the glasses. These three ions-doped phosphate glasses are potential candidates for white light-emitting diodes.
