CERTAIN CHARACTERISTICS OF RADIATIVE CENTERS IN SYNTHETIC GERMANIUM-DOPED QUARTZ,
Abstract
Electron paramagnetic resonance (EPR) was used in an investigation of the radiative defects in crystalline quartz activated with impurities of germanium, aluminum, and some alkali metals. Al impurities appear independently on the spectrum. Several tens of millions of roentgens are required to saturate the Griffiths-Owen-Ward (GOW) centers; smaller doses, of the order of several millions of roentgens, are required to saturate the 1 and 2 centers. The GOW and 1 and 2 centers are shown to appear as the result of irradiation and disappear, independently of each other, as the result of thermal or optical annealing. Investigation of the absorption spectra showed also that GOW and 1 and 2 centers exist independently from each other, have different probabilities of formation under the effect of ionizing radiation, and can be annealed independently when heated or illuminated.
