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.   Overview of the Shanghai EBIT 期刊论文  OAI收割 JOURNAL OF INSTRUMENTATION, 2010, 卷号: 5, 页码: 10 作者:  Fu, Y.;  Yao, K.;  Wei, B.;  Lu, D.;  Hutton, R.   |  收藏  |  浏览/下载：21/0  |  提交时间：2018/05/31 Ion sources (positive ions, negative ions, electron cyclotron resonance (ECR), electron beam (EBIS))  Plasma diagnostics - charged-particle spectroscopy  Ionization and excitation processes   The generalized oscillator strengths of hydrogenlike ions in debye plasmas 期刊论文  iSwitch采集 Physics of plasmas, 2009, 卷号: 16, 期号: 2, 页码: 9 作者:  Qi, Y.

W. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 In this paper  highly oriented and vertically arranged ZnO nanotubes are prepared on Al2O3 (0 0 0 1) substrate without employing any metal catalysts by plasma-assisted molecular beam epitaxy. The photoluminescence (PL) spectra at room temperature are studied under high excitation densities. Under lower excitation density (60 kW/cm2)  PL spectrum shows that one strong free exciton emission (FE) locates at 3.306 eV. As the excitation density increases up to 200 kW/cm2  a new emission peak (Pn) located at low-energy side of FE is attributed to the spontaneous emission due to an exciton-exciton (Ex-E x) scattering process from two ground state excitons  where one exciton is recombined by emitting a photon and the other is scattered into the excited states of n=2  3  4.... Under excitation density of 300 kW/cm 2  the stimulated emission originating from Ex-E x scattering is obtained. When the excitation density is above 580 kW/cm2  the emission from electron-hole plasma is observed in low-energy side of the P band and indicates a typical superradiation recombination processes with increasing excitation density. 2006 Elsevier B.V.
