摘要： 制备了掺Tm3+离子GICZPS玻璃:20GaF3-15InF3-20CdF2-15ZnF2-18PbF2-10SnF2- 2TmF3,用Judd-Ofelt理论计算了玻璃的光学参数,研究了玻璃的发光性质,并探讨了其发光 机理.结果表明,在641nm激发下,可以观察到485nm(1G4→3H6)和528nm(1D2→3H5)两 个上转换荧光发射峰.

关键词: Tm3+, Judd-Ofelt理论, 上转换

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
