- Abstract
- Reverse micelle chemistry-derived Cu-doped Zn1-xCdxS quantum dots (QDs) with the composition (x) of 0, 0.5, 1 are reported. The Cu emission was found to be dependent on the host composition of QDs. While a dim green/orange emission was observed from ZnS:Cu QDs, a relatively strong red emission Could be obtained from CdS:Cu and Zn0.5Cd0.5S:Cu QDs. Luminescent properties of undoped QDs versus Cu-doped ones and quantum yields of alloyed ZnCdS versus CdS QDs are compared and discussed. To enhance Cu-related red emission of CdS:Cu and Zn0.5Cd0.5S:Cu core QDs, core/shell structured QDs with a wider band gap of ZnS shell are also demonstrated. (C) 2009 Elsevier Inc.
