Abstract :
CdTe/Cd1-xMnxS core-shell structure nanoparticles were successfully synthesized in aqueous solution assisted by microwave irradiation. The photoluminescence spectra showed that incorporating low level Mn2+ in outer inorganic shell will not quench the photoemission of quantum dots. The doped nanocrystals exhibited high photoluminescence quantum yield (PLQY), reaching 52% in water under optimum condition.
