Summary: | <p>Abstract</p> <p>CdSe quantum dots with a prominent band-edge photoluminescence were obtained by a soft AOT water-in-oil (w/o) microemulsion templating method with an estimated size of 2.7 nm. The CdSe particles were covered with a TiO<sub>2 </sub>layer using an intermediate SiO<sub>2 </sub>coupling reagent by a sol-gel process. The resulting CdSe/TiO<sub>2 </sub>core/shell nanoparticles showed appreciable photocatalytic activity at λ = 405 nm which can only originate because of electron injection from the conduction band of CdSe to that of TiO<sub>2</sub>.</p> |
