Luminescence of Crystals Excited by a Excilamps

The photoluminescence spectra of six diamond samples under the action of excilamp radiation at wavelengths of 172, 206, 222, 282 and 308 nm was studied. The influence of the wavelength on the excitation of the centers of the band-A, the 3H center, and the 1.4 eV center is revealed. The luminescence of the 2.56 eV centers and the H3 center was observed for all excitation wavelengths.
