Microwave induced center-doping of silver ions in aqueous CdS nanocrystals with tunable, impurity and visible emission

Abstract

Under microwave radiation, Ag(+)-doped CdS semiconductor nanocrystals with high photoluminescence quantum yield (approximately 58%) and a surprisingly large optical window (480 to 630 nm) are formed controllably using a center-doping strategy and are optimized through a green approach in pure water solution.
