For the first time, β-Ga2O3 ceramics were synthesized by the electron beam method. The presence of a pulsed cathodoluminescence band at 2.75 eV was found. It has been shown that the thermoluminescence curve of the obtained ceramics is described by the sum of two elementary peaks of second order kinetics. The calculated values of the energy depths of traps and frequency factors indicate differences in the mechanisms of formation of the luminescent response of ceramics synthesized by the electron beam method, compared with single crystals and ceramics obtained by other methods. Keywords: oxide ceramics, thermoluminescence, cathodoluminescence, kinetic parameters.
