Abstract

The two alkaline earth niobates Sr//2Nb//2O//7 and Ba//0//. //5Sr//0//. //5Nb//2O//6 have been prepared, their electronic properties measured, and their photoresponses compared. The indirect band gap in Sr//2Nb//2O//7 is 3. 86 eV compared with 3. 38 eV for Ba//0//. //5Sr//0//. //5Nb//2O//6. Hence, photoanodes composed of Sr//2Nb//2O//7 respond to much less of the ″white″ light spectrum than those made from Ba//0//. //5Sr//0//. //5Nb//2O//6. Nevertheless, their electrical outputs at anode potential of 0. 8 eV with respect to SCE in 0. 2 M sodium acetate under ″white″ xenon arc irradiation of 1. 25 W/cm**2 are comparable.
