On the photoluminescence of semiconducting titanates applied in photoelectrochemical cells
Abstract
We report on the photoluminescence of the semiconducting titanates TiO 2 (rutile), SrTiO 3, MgTiO 3, K 1.8Mg 0.9Ti 7.1O 16, and La 2Ti 2O 7, which are known to act as photoanodes in a photoelectrochemical cell. For all materials, except TiO 2 (rutile), self-trapped exciton emission from a titanate group is observed at LHeT. The importance of the self-trapped excited state is discussed and related to the photoelectrochemical behavior of these semiconducting titanates.
