설명

일반 설명

Silver sulfide (Ag₂S) quantum dots (QD) are semiconducting inorganic nanoparticles, offered as a concentrated solution (10 mg/mL) in N,N-dimethylformamide. The most important property of a Ag₂S QD is its excitonic absorption peak wavelength, which is controlled by the particle size. These infrared Ag₂S quantum dots have an excitonic absorption peak wavelength of 800 nm and narrow peak width, indicating that they are a monodisperse ensemble of nanoparticles, all a very similar size. In addition, Ag₂S quantum dots do not contain toxic elements (such as Cd and Pb), making them a greener alternative to Cd- and Pb-based QDs.

애플리케이션

Ag₂S quantum dots have a range of potential applications in nanodiagnostics, solar cells, and photoelectrochemical biosensors. These nanocrystals can be used as NIR optical imaging probes in research activities aimed at studying nanodiagnostics and imaging in vivo. Additionally, studies have shown that Ag₂S QDs can serve as a highly efficient and broadband sensitizer for solar cells, making them a promising material for research and development activities in the field of photovoltaics[1] Ag₂S QDs have also demonstrated potential as PEC biosensors, with studies showing that they have extensive potential in this application due to their simplicity, low toxicity, sensitivity, and wide range of potential uses[2][3]
