SHORT-WAVELENGTH LUMINESCENCE AND THERMOSTIMULATED PROCESSES IN SINGLE-CRYSTALS OF BEO

The results of a study of thermostimulated luminescence and recombinat ion processes in pure and impure single crystals of BeO are reported. The origin of the trapping and recombination centers, their parameters (activation energies, frequency factors), the recombination schemes a nd the TL spectra were determined. It was shown that, in the BeO singl e crystals during electron and hole recombinations, the excitation of the intrinsic luminescence band at 4.9 eV proceeds and its characteris tics inherit no properties from the recombination centers.
