| 中文摘要 | 研究了La2O3对Yb：Y2O3透明陶瓷光谱性能的影响，添加适量La2O3以后，Yb：Y2O3透明陶瓷的吸收峰和发射峰的位置不变，但由于La^3＋的离子半径大于Y^3＋的离子半径，在Y2O3中引入La^3＋离子后，导致Y2O3晶格常数变大，晶场强度变弱，同时降低了Y2O3晶体的有序度，致使发射峰强度有所下降，发射截面变小．过量的№La2O3（x=0．16）造成yb^3＋激活离子发射强度明显下降；其荧光寿命在添加La2O3后总体增大45％-60％.; The effect of La2O3 doping on the spectroscopic properties of transparent Yb: Y2O3 ceramics was studied. After doping La2O3, the shapes and positions of the absorption and emission peaks of transparent (Yb0.05Y0.95-x La-x)(2)O-3 ceramics were almost the same as those of Yb:Y2O3. When La2O3 was added into Yb:Y2O3, the lattice constant of (Yb0.05Y0.95-xLax)(2)O-3 became large and the crystal field strength weaker due to introducing of larger radius of La3+ ion, simultaneously its degree of order is decreased, which results in the decrease of the emission intensities and the emission cross-sections. The emission intensities were reduced greatly for the excessive doping of La2O3 ( 16at%) in (Yb0.05Y0.95-x La-x)(2)O-3 ceramics. On the whole the fluorescent lifetimes of the samples are increased by 45%-60% after doping La2O3. |
