Overview
Description

Our CdS/ZnS & CdSSe/ZnS Quantum Dots quantum dots provide narrow-band fluorescence emission in the wavelength range of 420 nm to 520 nm. CdS/ZnS is a semiconductor nanoparticle, which is a typical direct bandgap compound of the IF VI group. Due to its large surface area and poor optical properties of quantum dots, ZnS is used as the shell layer to enhance its luminescence stability. CdSSe/ZnS is a ternary alloy quantum dot, which can absorb and cover the entire visible light band, thereby improving the performance of optical devices, which brings great application prospects.
