Abstract: Tm3+ doped GICZPS glass: 20GaF3-15InF3-20CdF2-15ZnF2-18PbF2-10SnF2-2TmF3 was produced. The intensity parameters of Tm3+ in this glass were calculated by Judd-Ofelt theory. The fluorescence properties of the glass were investigated, and the excitation mechanism of upconversion fluorescence was also discussed. The conclusion can be drawn that the emission at 485nm(1G43H6) and 528nm(1D23H5) can be obtained under 641nm excitation.

Key words: Tm3+, Judd-Ofelt theory, upconversion
