退火温度对Ce∶YAlO_3单晶体的影响研究(英文)

Effects of Annealing Temperature on Ce∶YAlO_3 Single Crystal

将生长完成的Ce∶YAlO3单晶体在1680℃的高温氢气气氛下退火,晶体颜色、吸收光谱和荧光光谱相对于未退火的样品均发生了变化。本文对此现象进行了分析。研究结果表明,1680℃高温氢气退火后,Ce∶YAP晶体中同时包含YAP相和YAG相。

As-grown Ce∶YAlO3（Ce∶YAP） single crystal was annealed at 1680 ℃ in H2 atmosphere.The phenomena including color changes,absorption spectra changes and fluorescence spectra changes were observed and analyzed.All results indicate that the H2-annealed Ce∶YAP crystal contains both YAP phase and YAG phase.
