Description

Application

The size for our lead sulfide (PbS) quantum dots (QDs) varies between 2.5 to 8 nm and depending upon this, these QDs emit between 900-1600 nm. Our PbS QDs possess high quantum yield, sharp emission and exhibit narrow fluorescence band (full width at half maximum <100 nm), which make them suitable as light absorber or IR emitter in applications in solar cells, photodetectors and infrared light emitting diodes (LEDs).
