	Mechanisms of energy transfer in Pr3+ and Cr3+ codoped SrAl12O19 phosphor (EI CONFERENCE) 会议论文 OAI收割 209th ECS Meeting, May 7, 2006 - May 12, 2006, Denver, CO, United states 作者: Zhang J.; Wang X.-J.; Zhang G.; Zhang G.; Zhang G. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 A two-step energy transfer was observed in Pr3+ and Cr 3+ codoped SrAl12O19 phosphor which results in a two-photon luminescence for one UV/vacuum-UV photon absorbed. For one Pr 3+ ion excited to the lowest 4f5d states two Cr3+ ions may be excited and emit two red photons due to 2E- 4A2 transitions of the Cr3+ ions Cr 3+ ions can be excited into the 4T1(F) levels by cross relaxation of Pr3+ 1S0- 1I6 or by direct energy transfer from Pr3+ 3P0 1 states. The mechanisms of the two-step energy transfer process were studied based on spectra and lifetime measurements. copyright The Electrochemical Society.
