Abstract
We report on non-steady-state photocurrent measurements of photorefractive sillenites grown in an oxygen-free atmosphere. A sufficient increase in the photoconductivity of crystals grown in an argon atmosphere in the red regi on of the spectrum (lambda = 633 nm) was observed. We attribute such change s to the high density of oxygen vacancies, and we present investigations of the influence of oxygen vacancies on the energy spectrum and on the parame ters of photoinduced carriers in photorefractive sillenites.
