	Luminescence and energy transfer in Ca3Sc2Si 3O12:Ce3+,Mn2+ white LED phosphors (EI CONFERENCE) 会议论文 OAI收割作者: Luo Y.; Zhang J.; Zhang J.; Zhang J.; Wang X. 收藏 \| 浏览/下载：45/0 \| 提交时间：2013/03/25 Expanded emission spectra ranging from green to red are reported in Ca 3Sc2Si3O12 (CSS):Ce 3+ Mn2+ silicate garnets. Mn2+ may occupy Ca2 site (Mn2+(I)) to generate a yellow emission band at 574 nm or Sc3 site (Mn2+(II)) with red emission band at 680 nm. Efficient energy transfers from the green emitting Ce3+ to both Mn2+(I) and Mn2+(II) occur upon blue excitation into Ce3+. Concentration dependence of Mn2+ emission is analyzed based on Ce3+-Mn2+ energy transfer steady state rate equations and fluorescence lifetimes. Energy transfer efficiency (nT) and rate (W) are calculated with values as high as 45% and 14.01106 s-1 respectively. 2011 Elsevier B.V.
	Energy transfer in Y3Al5O12:Ce 3, Pr3+ and CaMoO4:Sm3, Eu 3 phosphors (EI CONFERENCE) 会议论文 OAI收割作者: Wang L.; Wang X.-J.; Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：44/0 \| 提交时间：2013/03/25 Non-radiative energy transfers (ET) from Ce3 to Pr3+ in Y3Al5O12:Ce3 Pr3+ and from Sm3 to Eu3 in CaMoO4:Sm3 Eu3 are studied based on photoluminescence spectroscopy and fluorescence decay patterns. The result indicates an electric dipoledipole interaction that governs ET in the LED phosphors. For Ce3 concentration of 0.01 in YAG:Ce3 Pr3+ the rate constant and critical distance are evaluated to be 4.510-36 cm 6 s-1 and 0.81 nm respectively. An increase in the red emission line of Pr3+ relative to the yellow emission band of Ce 3 on increasing Ce3 concentration is observed. This behavior is attributed to the increase of spectral overlap integrals between Ce3 emission and Pr3+ excitation due to the fact that the yellow band shifts to the red spectral side with increasing Ce3 concentration. In CaMoO4:Sm3 Eu3 Sm 3Eu3 transfer occurs from 4G5/2 of Sm3 to 5D0 of Eu3. The rate constant of 8.510-40 cm6 s-1 and the critical transfer distance of 0.89 nm are evaluated. 2010 Elsevier B.V.

	Energy transition between Yb3+-Tm3+-Gd3+ in Gd3+, Yb3+ and Tm3+ Co-doped fluoride nanocrystals (EI CONFERENCE) 会议论文 OAI收割 17th International Conference on Dynamical Processes in Excited States of Solids, DPC'10, June 20, 2010 - June 25, 2010, Argonne, IL, United states 作者: Zhang J.; Zhang J.; Zhang J. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 YF3: 20%Gd3+ 20%Yb3+ 0.5%Tm3+ nanocrystal has been synthesized by a hydrothermal method. 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.

	Anti-stokes fluorescent cooling by energy transfer (EI CONFERENCE) 会议论文 OAI收割作者: 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 A new model on the mechanism of anti-Stokes fluorescent cooling is proposed based on which incident laser induces a phonon-assisted energy transfer from one luminescent center to another in an optical medium and causes medium cooling when the energy transfer is an anti-Stokes process and absorbs phonons. Here we develop the model in two cases: two-phonon-assisted energy transfer for a small energy mismatch and one-phonon-assisted energy transfer for a large energy mismatch. The dependence of relative cooling efficiency on photon energy and temperature is also discussed in evaluating the new mechanism. 2006 Elsevier B.V. All rights reserved.
	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：23/0 \| 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.
