应用
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).

A solution-based passivation scheme is developed featuring the use of molecular iodine and PbS colloidal quantum dots (CQDs). The improved passivation translates into a longer carrier diffusion length in the solid film. This allows thicker solar-cell devices to be built

The detection of photons underpins imaging, spectroscopy, fibre-optic communications and time-gated distance measurements. Nanostructured materials are attractive for detection applications because they can be integrated with conventional silicon electronics and flexible, large-area substrates, and can be processed from the solution
