Microwave assisted robust aqueous synthesis of Mn²⁺-doped CdSe QDs with enhanced electronic properties.

ABSTRACT: A robust doping strategy of Mn²⁺ ions in CdSe QDs has been developed in aqueous medium with mild microwave irradiation using the short-chain capping ligand 3-MPA. The concentration of the dopant is varied stoichiometrically in order to measure its effect on the conductivity of QD solids for further potential applications in the future. The synthesis parameters of CdSe QDs have been optimized to produce a uniform size among various samples to decouple the doping dependent conductivity from their bandgap. Doping yield is measured extensively by several studies like EDS, ICP-AES, and XPS. The layer-by-layer electrostatic assembly method has been exploited to fabricate thin film devices. I-V characteristics reveal that the electrical conductivity of 2% Mn²⁺-
