NY, United States – September 29, 2021 /MarketersMEDIA/ —

The charm of quantum dot nanotechnology has been noticed by many electronic and biomedical industries. Earlier this year, Alfa Chemistry announces that now CdS/ZnS quantum dots are readily available for customers worldwide.

Among the many types of II-VI group semiconductor quantum dots including CdS, ZnS, CdSe, ZnSe and so on, CdS/ZnS quantum dots have been most intensively studied for its light-emitting potential application in recent years.

“This is because they can absorb excitation light to produce fluorescence, and the wavelength of fluorescence emission can be adjusted by changing the size of the quantum dots. Moreover, in order to enhance the luminescence stability of CdS quantum dots, wideband gap semiconductor particle ZnS is used as the shell to coat narrowband gap semiconductor particle CdS. Through such a way, a core-shell CdS/ZnS quantum dots is fabricated and enjoys not only enhanced fluorescence quantum yield but also decreased cytotoxicity, making it possible to be used in biomedical engineering,” says the Marketing Chief of Alfa Chemistry.

According to the solubility, CdS/ZnS quantum dots can be divided into water-soluble CdS/ZnS quantum dots and non-water-soluble CdS/ZnS quantum dots. “Currently, we offer cadmuim sulphide/zinc sulphide-PEG-NH₂ quantum dots with a purity of 99.9%.”

Except for CdS/ZnS quantum dots, many other forms of quantum dots are also available, to name just a few here: alloyed quantum dots, cadmium free quantum dots, carbon dots, InP ZnS quantum dots, PbSe/PbS quantum dots, upconverting nanoparticles (UCNPs), ZnSe/ZnS quantum dots, etc.

About Application of CdS/ZnS quantum
Compared with traditional fluorescent dyes, CdS/ZnS quantum dots are a promising fluorescent probe due to merits such as high fluorescence quantum yield, stable luminescence, wide excitation spectrum, narrow emission spectrum and tunable fluorescence. Also, CdS/ZnS quantum dots can be used when designing solar cells to make them of low cost, good stability and long life. Solar cells will provide green and sustainable energy. In addition, CdS/ZnS quantum dots are also widely used in many fields, such as light-emitting diodes, cell imaging, biosensors and the others.
