Abstract

Measurements of emission spectra and decay times of Eu3+, Sm3+ Tb3+, Dy3+ and Gd3+ and their concentration dependence were taken in silicate glasses, in the concentration range 0.05–1.00 weight percent, under monochromatic excitation. The results are compared with those obtained in borate glasses. The lower intensities of the main emission lines for all the five R. E., the longer decay times for Tb3+ and Sm3+ and the shift to shorter wavelengths for Eu3+ and Sm3+ are explained in terms of the lower field strength seen by the R. E. in silicate glasses and smaller energy transfer probabilities.
