Study on the green upconversion saturation in Er3+ doped oxyfluoride tellurite glass董力强1,2,黄世华1,温红宇2,康凯1,段晓霞11. Key Laboratory of Luminescence and Optical Information (Ministry of Education... was analyzed. Quadratic intensity dependence was only observed at weak excitation intensity. With increasing the excitation intensity, saturation was turned out. The experimental results were fitted......
displacement, and curves of saturation degree versus time are investigated. The results show that the specimens with similar curves of saturation degree versus time have nearly identical mechanical behavior. In particular, the uniform specimens should be chosen within the lower equilibrium saturation degree because steady test results are presented. Further, the conclusion is verified......
