The mechanism of radical-recombination luminescence in zinc oxide

The temperature-time relationships of the intensity of radical-recombination luminescence (RRL) and the surface electroconductivity of zinc oxide with excitation by atomic hydrogen have been studied. The results are analyzed on the basis of the electron theory of chemisorption and catalysis and the band theory of crystal-phosphor luminescence. The effect of the state of the gas phase and the deep trapping level on the intensity of the RRL is elucidated. A mechanism is proposed for the RRL excitation of this phosphor.Translated from Izvestiya VUZ. Fizika, No. 12, pp. 19–24, December, 1973.
