	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：36/0 \| 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.

	The spectral feature analysis of semiconductor thin disk laser (EI CONFERENCE) 会议论文 OAI收割 Optoelectronic Materials and Devices II, November 2, 2007 - November 5, 2007, Wuhan, China 作者: Li J.; Wang L.-J.; Wang L.-J.; Ning Y.-Q.; Li J. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 The semiconductor thin disk laser is a new type of semiconductor laser. This work gives the basic operation function of semiconductor disk laser and analyses the heat effect by the experimentally measured photoluminescence spectrum of the laser chip at different pump power and different temperature. We can see that: with increasing pump power the thermal effects of the gain material becomes seriously and causes the saturation of carrier lifetime so the electron-hole pair created in the absorbtion layer have no enough time to rate to one of the wells and the non-radiative recombination happens in the barrier. When the thermal effects becomes stronger the chip will not lasing. This phenomenon is from the smaller energy offset between barrier and quantum well. We optimize the original structure design and experimental technology. A non-absorbing AlGaAs layer who is transparent to the pumping and laser wavelength is added to confine the carriers in the quantum wells. At the same time a DBR with double reflecting band is induced to improve the absorbing efficiency of the pumping light. The single QW is replaced by the three narrow QWs This three QWs structure can add the quantum state of QW increase the recombination probability of carriers in the QWs and reduce the heat effect. The chemical etch equipment is also improved to control the surface unevenness to be within 50 nm.
