Synthesis of White Light Emitting Water-soluble CdZnS Quantum Dots at Room TemperatureBy Abhijit Mandal
Abstract: Water-soluble alloyed CdZnS quantum dots (QDs) have been successfully prepared at room temperatures by reacting a mixture of Cd(CH3COO)2 and Zn(CH3COO)2 with Na2S using thiolactic acid (TLA) as a surface capping agent. The photoluminescence (PL) spectra of the alloyed QDs are determined on the basis of the Cd2+/Zn2+ molar ratio, reaction pH, intrinsic Cd2+and Zn2+reactivities toward Na2S and the concentration of capping agent. A systematic blue shift in emission wavelength …
