In this NJC Hot paper Chinese researchers (Soochow University and Jiangsu University) describe a facile route for the fabrication of porous and solid SrTiO3 films by a template-free hydrothermal method using TiO2 NTs precursor and loading CQDs on the SrTiO3 surface by electrodeposition. As a result, the CQDs–SrTiO3 is responsive under near NIR irradiation owing to the energy upconversion ability of the CQDs. Based on the their results, a possible electron–hole transfer mechanism was also assumed.
