| 中文摘要 | With the help of absorption and fluorescence spectra, the spectroscopic properties of Tm3+, Ho3+:YVO4 crystals have been investigated under different dopant concentrations. The absorption results show that the maximum absorption in the spectral range of currently available powerful laser diodes (LD) is at 796 nm, corresponding to the transition H-3(6) --> H-3(4) Of Tm3+ in the crystals. Upon the excitation with a LD at 808 nm, we have detected ten fluorescence bands in the spectral range spanning from visible to infrared. In visible region 4 upconversion bands have been observed centered at 475, 547, 660, and 701nm. Discussions of the energy transfer processes suggest that cross relaxations and excited absorptions with the involvement of Tm3+ F-3(4), H-3(5) and Ho3+ 7I(5) states are responsible for the four upconversion emissions. Comprising the relative integrated intersities of 2 mu m (Ho3+: I-5(7) --> I-3(8)) and 1.8 mu m (Tm3+:F-3(4) --> H-3(6)) bands we have observed an efficient energy transfer from Tm3+ (F-3(4)) to Ho3+ (I-5(7)). Examination of the ratios of the intensity of 2 mu m band to that of 1.8 mu m band as a function of the ratios of Tm3+ concentration (c(Tm)) to Ho3+ concentration (c(Ho)) indicates that small concentration ratios (c(Tm)/c(Ho)) lead to high efficient energy transfers of Tm3+(F-3(4)) --> Ho3+(I-5(7)). |
