Application

Our PbS quantum dots have a fully crystalline inorganic core and are organically stabilized with an oleic acid coating, which makes their surface hydrophobic in nature. They exhibit high colloidal and thermal stability, as well as strong emissions with narrow fluorescence bands, owing to their small particle size distributions. These particles absorb all light in the UV, VIS and NIR, up to 900 nm. Their size-dependent absorption and emission properties make them suitable for different applications: such as, absorber materials in photovoltaics, detectors and photodiodes, and phosphors in IR-emitters (solid state lighting, SSL), among many others.
