Abstract
Spectroscopic properties of Ce-doped yttrium orthoaluminate (Ce:YAIO3 or Ce:YAP) crystals grown by temperature gradient technique (TGT) were investigated, and the effects of the growth conditions on the properties were analyzed. Methods of optical absorption (OA), photoluminescence (PL), photoluminescence decay (PLD), X-ray excited luminescence (XL) and cathodeluminescence (CL) were used in these investigations. The results showed that the absorption band peak at 202, 394 and 532 nm originated from F and F+ color center induced by the weak reducing growth atmosphere, green emission band near 500 nm derived from Ce3+ -Ce3+ pairs and band at 650 ∼ 850 nm from some unintentional impurity in crystals.
