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(1G4→3H6) and 528nm(1D2→3H5) can be obtained under 641nm excitation.

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