Abstract
tridoped phosphate glasses containing different ion concentrations were synthesized to explore new white-light-emitting material. Under excitation, the CIE coordinates (, ) of the Mn0.10 sample doped with are close to the standard equal energy white-light illumination (, ). The quantum efficiency of the Mn0.01 sample is very high (). The concentration of ions has a great effect on the emission color, and the energy transitions from , to become more intense with an increase in ion concentrations. The phenomenon is reasonably interpreted based on the analysis of the luminescence lifetime.
