Luminescent properties of Ce³⁺ ions in zinc phosphate glass prepared in air

Abstract

Glasses are prepared by sintering P₂O₅, ZnO and Ce₂(C₂O₄)₃ · 10H₂O mixtures at 1 100 °C in air and then annealed at 400 °C for 10 hours. The obtained glasses are homogeneous, transparent and colorless. Emission and excitation spectra are measured for the samples and the results show that the glasses contain Ce³⁺ trivalent cerium ions. The parameters of glass preparation obtained here may be adapted to preparing this type of glasses doped with other lanthanide ions, so as to study energy transfer phenomena and variation of radiative lifetime with refractive index due to local field effect.
