Due to its interesting physicochemical properties (good electrical conductivity, adequate specific surface area, and significant concentration of surface OH groups suitable for sylilation reactions), the ZnO sample, prepared by thermal decomposition of Zn4CO3(OH)6·H2O at 400 °C (named ZnO400), was selected as the host solid for the introduction of guest luminescent CdTe nanocrystals. The modification of the ZnO surface with CdTe allowed us to change the optical properties of the final solid, resulting in a tuning of emission properties of the ZnO nanosheets. %I ACS Publications
