	Excitonic properties of vertically aligned ZnO nanotubes under high-density excitation (EI CONFERENCE) 会议论文 OAI收割 Lu Y. M.; Liang H. W.; Shen D. Z.; Zhang Z. Z.; Zhang J. Y.; Zhao D. X.; Liu Y. C.; Fan X. 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.

	Energy upconversion in erbium doped oxyfluoride tellurite glass (EI CONFERENCE) 会议论文 OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者: Chen B.; Xie Y.; Wang X.; Wang X.; Wang X. 收藏 \| 浏览/下载：15/0 \| 提交时间：2013/03/25 In this article we have investigated energy upconversion process in erbium doped oxyfuoride tellurite glasses exciated with 980 nm diode laser. 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.
	Energy transfer in Pr3+- and Cr3+-codoped SrAl 12O19 system (EI CONFERENCE) 会议论文 OAI收割作者: Luo Y.; Zhang X.; Zhang X.; Zhang X.; Zhang J. 收藏 \| 浏览/下载：16/0 \| 提交时间：2013/03/25 The energy transfer processes in Pr3+- and Cr 3+-codoped SrAl12O19 system are studied experimentally. The transfer can convert the 1S0 ultraviolet fluorescence of Pr3+ into the red emission of Cr 3+. The 3P0 state which may be populated by 1S0&rarr1I6 emission can also act as a donor state in the transfer to Cr3+. Cross-relaxation process is reported firstly in energy transfer between the pair of Pr 3+-Cr3+ in SrAl12O19 system. Two-step energy transfer is discussed which involves two visible photons for each vacuum ultraviolet photon absorbed. 2006 Elsevier B.V. All rights reserved.
