Abstract

The SrTiO₃ films were synthesized by a hydrothermal method using TiO₂ nanotube arrays as the precursor. The photoanode of SrTiO₃ film decorated by carbon quantum dots (CQDs) is capable of converting near IR photon energy to photocurrent. Efficient carrier transfer and a high electron/hole separation rate of the hetero-junction between the CQDs and SrTiO₃ were achieved.
