Thermoluminescence Studies of Proton-Irradiated Cr-, Mg-Codoped β-Ga₂O₃.

ABSTRACT: Chromium-doped Ga₂O₃, with intense Cr³⁺-related red-infrared light emission, is a promising semiconductor material for optical sensors. This work constitutes a comprehensive study of the thermoluminescence properties of Cr-, Mg-codoped β-Ga₂O₃ single crystals, both prior to and after proton irradiation. The thermoluminescence investigation includes a thorough analysis of measurements with different β^- irradiation doses used to populate the trap levels, with preheating steps to disentangle overlapping peaks (T_M-T_STOP and initial rise methods) and finally by computationally fitting to a theoretical expression. At least three traps with activation energies of 0.84, 1.0, and 1.1 eV were detect
