Abstract: 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.
