Product Description

Oil-soluble HgTe quantum dots (HgTe QDs) are a class of semiconductor nanocrystals that exhibit tunable optical properties. Thanks to their SWIR spectral response and reliable stability, these QDs are widely investigated for applications such as infrared photodetectors, optical sensing, and advanced imaging technologies. Their unique optical properties also make them promising materials for developing next-generation infrared optoelectronic devices and research tools in nanotechnology and photonics.

Structural Characteristics

Oil-soluble HgTe QDs consist of an HgTe nanocrystal core with oleylamine as the surface ligand. The oleylamine molecules form a hydrophobic organic layer on the surface of the quantum dots, which effectively stabilizes the nanocrystals and prevents aggregation. In addition, this surface modification allows the quantum dots to remain well dispersed in nonpolar organic solvents such as hexane and toluene, facilitating their use in various material processing and research applications.

Key Characteristics

Oil-soluble HgTe QDs exhibit a broad spectral response covering the short-wave infrared (SWIR) region, with an absorption cutoff wavelength of approximately 2.5 μm. This characteristic makes them highly suitable for infrared detection and sensing technologies that operate in the SWIR spectral range. In addition, the presence of oleylamine surface ligands enhances the stability of the quantum dots by protecting the nanocrystal surface and preventing aggregation, thereby maintaining their structural integrity and optical performance over time.
