Abstract
The Tm3+/Er3+:NaGd(MoO4)2 crystal with dimensions of Φ22Ã30 mm3 was grown by Czochralski method. Polarized spectra and fluorescence lifetime for the 4I13/2(Er3+)â4I15/2(Er3+) transition at room temperature were investigated. Based on the Judd-Ofelt theory, the spontaneous transition probabilities, the fluorescent branching ratios and the radiative lifetimes were calculated. The fluorescence lifetime was measured to be 1.81 ms. The detailed excited-transition mechanism with 800 nm radiation is also discussed.
