摘　　要：采用提拉法成功生长了高光学质量掺杂浓度分别为0.2at%的Fe:YAP和0.5at%的Cu:YAP晶体.ICP-AES测试得出Fe、Cu离子在YAP晶体中的分凝系数分别为0.13和0.28.室温下测试了两种晶体经不同气氛高温退火后的吸收光谱和X射线激发发射光谱,分析了光谱特征及退火对光谱产生影响的微观机理.最后研究了两种晶体的热释光性能,发现Cu:YAP晶体是一种非常有潜力的辐照剂量计材料.High optical quality 0.2at% Fe doped YAP and 0.5at% Cu doped YAP single crystals were grown successfully by Czochralski method respectively.The separation coefficients of Fe ion in 0.2at% Fe doped YAP and Cu ion in 0.5at% Cu doped YAP crystals determined by ICP-AES method were 0.13 and 0.28 respectively.The absorption spectra and X-ray excitation luminescence spectra of the Fe：YAP and Cu：YAP crystals annealed in reduction/oxidation atmosphere were measured at room temperature.Microcosmic mechanisms of the spectra characteristics and the effects of anneal on crystals were analyzed.Finally,the thermoluminescence spectra of Fe：YAP and Cu：YAP crystals were also studied.It is found that Cu：YAP crystal is a prospective dosimetry material.
