Their appearance was explained, and corresponding mechanisms were proposed. The changes in the luminescence and scintillation properties were characterised by photo- and radioluminescence, respectively. Charge trapping phenomena were studied by thermally stimulated luminescence. Cold plasma treatment influences the luminescence properties of ZnO:Mo structures. The contact with hydrogen leads to the about triple intensity increase of the ultraviolet exciton-related band peaking at ~3.24 eV, whereas the red band attributed to zinc vacancies (~1.97 eV) was suppressed compared to the as-grown samples. The exciton- as well as defects-related emission subsided after the treatment in oxygen plasma.
