Optical and Luminescence Properties of YAlO₃-Tm Crystals

The results on optical absorption, photoluminescence and thermoluminescence of YAP-Tm crystals of 1 at.% and 4 at.% of Tm are presented as well as influence of UV-, γ-radiation and thermal treatments on optical and luminescence properties of the crystals. The blue-green luminescence of defect centers was observed in YAP-Tm crystals at Ar⁺-laser excitation. The possibility of energy transfer processes between defect centers and Tm³⁺ ions was shown.

Keywords: YAlO3-Tm, optical absorption, luminescence, color centers
