CdS/ZnS Quantum Dots Are Now Available at Alfa Chemistry
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...
