White emission from Tm3＋/Tb3＋/Eu3＋ co-doped fluoride zirconate under ultraviolet excitation

We synthesize Tm3＋/Tb3＋/Eu3＋ triply-doped ZrF4-BaF2-LaF3-A1F3-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...

Summary:We synthesize Tm3＋/Tb3＋/Eu3＋ triply-doped ZrF4-BaF2-LaF3-A1F3-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.
