ABSTRACT: We report on the experimental study of the visible and
ultraviolet (UV) fluorescence emission in a (1% molar) Thulium (Tm+3)-doped
Zirconium fluoride glass sample. From red at 650 nm, blue (453 & 480 nm) and UV
at 365 & 284 nm, have been observed under excitation of a Nd:YAG laser at
1.064 μm. The responsible up-conversion mechanisms are investigated based on
experimental data. The related problem of photo-degradation associated with
formation of color centers is also addressed.
