Abstract

This paper presents the study on the Mn-doped ZnS (ZnS:Mn) nanoparticles synthesized using reverse micelle method assisted by compressed CO2 at 60 bar and 40°C. Effects of retention time (30-120 min) on the particle formation were studied. The optical properties, size, morphology, and structure of the resulting particles were investigated. The results showed that ZnS:Mn nanoparticles were successfully formed with particle size ranging from 2 to 3 nm, which showed quantum size effects. The highest photoluminescence (PL) intensity ratio was found at 60 min retention time. The increase in photoluminescence (PL) intensity ratio indicated an increased homogeneity of nanoparticle growth with decreased surface defects.
