We study decay kinetics of the 410 nm Ce emission in the SrHfO₃ host. Measurement of the prompt and also delayed recombination decay put in evidence the thermally induced ionization of the Ce³⁺ excited state. An additional proof is obtained by observation of the thermally stimulated luminescence signal after the UV excitation of the Ce emission center.
