Characterization of ZnS Nanoparticles Using MPA as Capping Agents

Abstract:

In this study, the synthesis and characterization of ZnS nanoparticles in aqueous solution precipitation using MPA as capping agents were reported. The 3-mercaptopropionic acid (MPA) was used as the capping agent to control the size of the ZnS nanoparticles. We found that the particles size of ZnS using MPA as capping agent was less than 10nm; ranging from 6-8 nm in size and sphere in shape using TEM measurements. Meanwhile, the photoluminescence and optical absorption were collected using Spectrofluorometer. As the results, the emission band for photoluminescence spectra was blue (~ 425 nm) appeared for samples before refluxed. For samples which were refluxed for 7 hours, the photoluminescence consists of a peak at 385 nm.
