PHOTOSTIMULATED TRANSFORMATIONS OF RADIATION COLOR CENTERS
OF SrCl2–Ce CRYSTALS
O. T. Antonyak* and N. S. Pidzyrailo
Spectra of x-ray radiation-induced absorption of SrCl2–Ce
crystals in the region of 340-830 nm under the effect of selective irradiation
in the induced-absorption bands by both conventional and laser sources
are investigated. It is established that irradiation of sufficient intensity
causes irreversible photochemical transformations of PC, PC+,
and Ce2+ color centers, their destruction, and restoration of
the transparency of the crystals.
