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.   ON PP TYPE ESTIMATED KOLMOGOROV STATISTICS 期刊论文  OAI收割 数学年刊：B辑英文版, 1992, 卷号: 000, 期号: 003, 页码: 280-288 作者:  Zhu LX(朱力行);  Cheng P(成平)   |  收藏  |  浏览/下载：22/0  |  提交时间：2021/01/14 Kolmogorov  argument  symmetry  spher  Adler  帕阿  subset  implies  uniformly  differentiable   ELEMENTAL ABUNDANCES OF NINGQIANG CHONDRITE 期刊论文  OAI收割 Science Bulletin, 1986, 期号: 2, 页码: 111-114 作者:  Chai ZF(柴之芳);  Mao XY(毛雪瑛);  Ma SL(马淑兰);  Wang SC(王思潮) 收藏  |  浏览/下载：25/0  |  提交时间：2015/12/07 favorable  chance  belongs  territory  irradiation  preliminary  agate  grateful  instrumental  implies
