Abstract
Using the micro-pulling-down method, Pr3+-doped YAlO3 single crystals were grown and their optical and luminescence properties were investigated within 80-300 K. Dominant 5d-4f emission was observed both in radio- and photoluminescence accompanied by weak f-f luminescence at 495 and 620 nm. The 5d-4f emission shows almost no temperature dependence up to 300 K and achieved radioluminescence intensity is more than 15 times higher than that of Bi4Ge3O12. High enough concentration of Pr3+ in YAlO3 host can be achieved to observe the onset of concentration quenching in the values and temperature dependence of the photoluminescence decay times.
