Synthesize of CdS nanoparticles using liquid-gas method

Abstract

In this paper, Cadmium Sulfide (CdS) nanoparticles (NPs) was synthesized using Liquid-Gas method. After CdCl2 mixed with surfactant in liquid phase, the mixture was exposed to S2 gas from brimstone. The solution changes color to yellow which means that the CdS NPs semiconductor has been formed. It was approved by the blue-shifted of the absorption spectra of CdS colloid solution then the size (radius) of CdS NPs would be determined by using the Efros equation. The radius yielded was about 2 nm. FTIR result also confirmed the CdS bond at 509 cm−1.
