Abstract
Abstract Sb 3+ /Mn 2+ co-doped phosphate glasses were prepared to explore efficient white-light materials. Under 275 nm excitation, the emission colors of the samples can vary from blue to red by adjusting Mn 2+ ion concentration. The emission color of the sample doped with 2 mol% Mn 2+ ion is white to the naked eye, and the CIE coordinates (0.336, 0.319) of the sample are close to the standard equal energy white-light illumination ( x = 0.333, y = 0.333). The energy transition efficiency of the sample is about 64.2%. Our research will be helpful in developing white-light materials.
