| 摘 要： | 用无水乙醇、冰醋酸、钛酸丁酯凝胶法制备了掺杂Er^3＋的TiO2粉末，测量了其在488m激发下的Stokes发射光谱和980nm激发下的上转换发光光谱。在可见光范围内，观察到了绿光和红光，绿光从500-570nm，对应Er^3＋的^2H11/2,^4S3／2→^4I15/2，红光从650～690m，对应Er^3＋的^4F9／2→^4I15／2的跃迁。由ln Ivis-In Iin曲线可知，绿光和红光均为双光子过程，光强正比于泵浦功率的二次方，即Iout ∝Iin。初步研究了此材料的上转换过程。

| Abstract: | Spectral property of Er3+-doped TiO2 prepared with gel method using absolute alcohol, glacial acetic acid and tetrabutyl titanate was studied. The Stokes emission spectra at 488 nm and upconversion emission spectra at 980 nm of the material were measured. In the visible range, green and red light was observed with green light corresponding to 2H(11/2), 4S(3/2)-->4I(15/2) transition of Er3+, and red light corresponding to 4F(9/2)-->4I(15/2) transition of Er3+. The green and red light are both two-phonon process from the curve of In Ivis-ln Iin, as the light intensity is directly proportional to the square of pump power. Elementary studies of the upconversion process were conducted. |
