摘要： We synthesize Tm3+/Tb3+/Eu3+ triply-doped ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) transparent glass by using a melt-quenching method. Under excitation of 365 nm, the white emission with Commission internationale deL'Eclairage (CIE) coordinates of (0.33, 0.33) is achieved at the Eu3+ concentration of 1.1 mol%. The mechanisms for white emission and the energy transfer process of Tb3+→Eu3+ are discussed in terms of the photoluminescence, photoluminescence excitation spectra, and the light emission decay curves. The nature for the Tb3+→Eu3+ energy transfer is described with the aid of an energy level diagram.
