摘要: The effect of 1.7 MeV electrons on the coloration Yb 3+ doped BaF 2 /ThF 4 base fluoride glasses has been investigated. Irradiation at 80 K produces a prominent absorption band 302 nm. At room temperature, radiation induced is quite small in these when compared with fluorizirconate glasses. photochemical damage mechanism dominant. optical and emission spectra as well fluorescence lifetime ion transitions have measured. measured lifetimes are calculated radiative lifetimes.
