Hybrid SiO2‐coated CdTe/CdSe quantum dots (QDs) were prepared using CdTe/CdSe QDs prepared by hydrothermal synthesis. A CdSe interlayer made CdTe/CdSe cores with unique type II heterostructures. The hybrid SiO2‐coated CdTe/CdSe QDs revealed excellent photoluminescence (PL) properties compared with hybrid SiO2‐coated CdTe QDs. Because of the existence of spatial separations of carriers in the type...
Novel hybrid SiO2‐coated CdTe quantum dots (QDs) were created using CdTe QDs coated with a hybrid SiO2 shell containing Cd2+ ions and a sulfur source via a sol–gel process in aqueous solution. Aqueous CdTe QDs with tunable emitting color created through a reaction between cadmium chloride and sodium hydrogen telluride was used as cores for the preparation of hybrid SiO2‐coated CdTe QDs. In our experiments...
