摘要：Silicate and phosphate glasses co-doped with rare-earth ions (REIs)(Ce3+, Tb3+, Eu3+) are presented in the present work. Their photoluminescence properties were studied by excitation and emission spectra. A combination of blue, green and red bands is shown for both silicate and phosphate glasses that allows the observation of white light when the glass is excited by UV light. The relative emission intensity ratios of the green to the red can be tuned by varying the concentrations of activator and/or sensitizer as well as the composition of glass matrices.
