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.
