| 摘 要： | 根据pr3+掺杂透明氟氧化物玻璃陶瓷(Pr(0.2)∶FOV)样品在室温下的吸收光谱,分别采用了标准和修正的Judd-Ofelt理论拟合出J-O强度三参量Mn.结果表明,此修正的J-O理论应用到Pr(0.2):FOV材料的跃迁强度计算中是合理的和必要的.并由此修正理论计算了各个激发态之间跃迁的振子强度、自发辐射速率、荧...

| Abstract: | In the present paper, the room-temperature absorption spectrum of Pr+ -doped transparent oxyfluoride vitroceramics (Pr(0.2):FOV) was studied systematically. The optical characterisation of Pr(0.2):FOV was performed. The standard and modified Judd-Ofelt theories were used to determine the J-O intensity parameters. The problems with standard Judd-Ofelt theorie for Pr3+ were discussed. Based on the intensity parameters, some predicted optical parameters, such as the spontaneous radiative transition probabilities, radiative lifetimes, branching ratios and integrated emission cross section were calculated. And the application of Pr:FOV was analyzed. Especially there are large oscillator strength and large integrated emission cross section in the transitions of (3)P0-->(3)H4, (3)P1-->(3)H5 and (3)P0-->(3)H6, (3)P0-->(3)F2. So, they are more worthy of attention. The obtained spectroscopic results show the potential application of the Pr3+ -doped oxyfluoride vitroceramics for solid-state lasers. |
