Abstract

Using the micro-pulling-down method, the undoped and Ce3+-doped PrAlO3 single crystals were grown. Absorption spectra and luminescence characteristics under UV and X-ray excitations were measured at room temperature. Weak 5d-4f emission of Pr3+ was found at 265 nm in the undoped sample. Energy transfer from the Pr3+ sublattice to Ce3+ ions seems plausible, but absence of efficient Ce3+ emission was found and explained as due to the positioning 5d1 relaxed excited state of Ce3+ within the host conduction band.
