Single nanocrystal spectroscopy identifies the interaction between zero-dimensional CdSe/ZnS nano crystals (quantum dots) and two-dimensional layered tin disulfide as a non-radiative energy transfer, whose strength increases with increasing number of tin disulfide layers. Such hybrid materials could be used in optoelectronic devices such as photovoltaic solar cells, light sensors, and LEDs. Credit: Brookhaven National Laboratory
It paves the way for better optoelectronic apps eg energy-harvesting photovoltaics, light sensors, LEDs. Scientists combined excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor...
