Abstract
We report preparation and characterisation of stable and size fixed Cu doped ZnO Quantum Dots. The unique luminescent properties have been observed at room temperature. The incorporation of Cu in the ZnO matrix is responsible for quenching the green luminescence at 530 nm arising due to native defect luminescence centres. Furthermore, luminescent transition which is attributable to the copper induced level at 422 nm is blue shifted from the analogical bulk feature at 433 nm and is visible in photoluminescence spectra even at room temperature.
