摘要: Fluorozirconate glass containing Eu3+ ions and chloride ions are prepared by a meltquenching method. The luminescence behavior of Eu3+ affected by Cl ions is investigated. With increasing Cl ion concentration, the luminous intensity of Eu3+ is significantly enhanced and the quantum efficiency of fluorozirconate glass is improved. Meanwhile, the intensity parameter Ω2 increases according to the Judd-Ofelt calculation, which indicates the decrease of local symmetry. The average lifetime of Eu3+ increases by introducing the Cl ions. Moreover, we find two kinds of sites for Eu3+ ions in a glass network by analyzing the fluorescence decay. The distribution of Eu3+ ions changes with increasing Cl ion concentration. In addition, the excessive Cl ions lead to the separation of the glass phase and the formation of the crystal phase, thus reducing the transmittance dramatically.
