Abstract Colour centers in YAlO 3 :Pr 3+ crystals originating under xenon lamp or y –radiation and oxidizing annealing are considered. The nature of colour centers under these treatments is similar in nominally pure and Pr 3+ containing crystals but the intensity of induced absorption lines is higher in activated crystals which assumably is associated with valent transitions of Pr ions.
