The glasses used in measurements are with a mol% composition of 70TeO2-9PbF2-190AlF3-10BaF2-1Er2O3. The s intensity parameters  the radiative rates  the branching ratios and the fluorescence lifetimes were calculated based upon the Judd-Ofelt theory and the experimental absorption spectrum. Under 980 nm excitation  efficient 530  544  and 665 nm upconversion emission are due to two-photon absorption processes.   半导体量子点非线性光学性能研究 学位论文  OAI收割 作者:  李京周   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/12/26 量子点  Quantum dots  非线性光学  Nonlinear optics  双光子吸收与发射  Two-photon absorption and emission  饱和吸收  Saturable absorption
