The size of them is about 600 nm 400 nm (side length thickness). The obtained sample was divided into two parts and one of them was annealed in nitrogen at 300 C for 2 hours. The crystal structure of the -NaYF4: Yb3+  Er3+ hexagonal sub-microplates before and after annealing treatment is hexagonal phase. Under the excitation of 980 nm diode laser  the upconversion luminescence intensity the sample after annealing is much stronger than that of the sample without annealing treatment. High temperature annealing process improved the crystallization of the sample  resulting in the decrease of the nonradiative relaxation and the enhancement of the upconversion luminescence.

The upconversion (UC) emission and energy transfer progresses between Gd3+-Yb 3+-Tm3+ under a 980-nm continuous wave semiconductor laser diode excitation have been explored. The experimental results show that the violet and ultraviolet (UV) enhancement with Tm3+ upconversion emission occurs in the nanocrystal  and in the same time the UC emissions of Gd3+ from 6D9/2  6IJ  6P5/2  and 6P7/2 states to the ground state 8S7/2 are obtained  too. The dynamic analysis implies that  under 980-nm excitation  the nanocrystal dimension plays a key role in the efficient energy transfer processes between Gd3+-Yb 3+-Tm3tt based on the energy matching conditions. 2011 Published by Elsevier B.V.   Tb3+/Yb3+ heavily-doped tellurite glasses with efficient green light emission 期刊论文  OAI收割 journal of non-crystalline solids, 2010, 卷号: 356, 期号: 50-51, 页码: 2896-2899 作者:  Zhou, Zhiguang;  Lin, Aoxiang;  Guo, Haitao;  Liu, Xueming;  Hou, Chaoqi 收藏  |  浏览/下载：24/0  |  提交时间：2010/12/02 Tellurites  Laser upconversion  Visible lasers  Fiber materials   Conversion of infrared radiation into visible emission in NaY(WO4)(2):Yb3+, Ho3+ crystal 期刊论文  OAI收割 Journal of Luminescence, 2010, 卷号: 130, 期号: 10, 页码: 1702-1707 X.
