Abstract
Glass, et al.,'1 discovered the bulk photovoltaic effect in doped lithium niobate crystals, and described the effect by the equation J = KaI, where J = current density, K = a constant whose value depends on the dopant and the light wavelength, a = absorp-tion coefficient, and I =.light intensity. In subsequent studies it was shown that for iron - doped crystals K varies significantly with the Fe2+ concentration. We propose to extend the description of the photovoltaic effect for iron by using the equation J = K1+ I, where K1 depends on light wavelength, but is independent of concentration, and aFe2+ (the absorption coefficient for the ionization of Fe2+) is proportional to Fe2-1- concentration. Experimental procedures will be described for making bulk photovoltaic measurements and using the extended equation for the characterization of commercial lithium niobate, where Fez+ is a trace contaminant, and a fe2+<< at wavelengths of 400 - 500 nm.
