1 Introduction Core/shell structured quantum dots (QDs) have received a significant interest due to their wide applications in biosensors, catalysis, photovoltaic devices, photodetectors, light–emitting diodes (LEDs), and other optoelectronic devices.[1-6] Their tunable energy band structures and optical properties (such as absorption and emission) achieved through the precise management of chemical composition enable a bottom-up design for tailored functionality and performance.[7, 8] It is...
