Abstract
Following growth doping technique, highly luminescent (quantum yield > 50%) Mn-doped ZnS nanocrystals are synthesized via colloidal synthetic technique. The dopant emission has been optimized with varying reaction parameters and found the ratio of Zn to S as well as the percentage of introduced dopant in the reaction mixture are key factors for controlling the intensity. The method is simple, hassle free, and can be scalable to gram level without hindering the quality of nanocrystals. These nanocrystals retain their emission during various ligand exchange processes and aqueous dispersion.
