Enhanced Characteristics of CdZnS Nanostructures by Using Capping Agents for Optoelectronic Applications

Abstract:

This study reports the impact of two distinct capping agents on the structural and optical properties of CdZnS nanoparticles (NPs) using an aqueous colloidal synthesis technique. The samples were characterized using SEM, UV-Visible, Photoluminescence (PL) spectroscopy and X-ray diffraction (XRD). In all of the synthesized samples, SEM exhibits a granular texture with uniform distribution of particles. The capping agent helps in crystallite size reduction and hexagonal structure. The variation in the band gap is caused by quantum confinement depicted in PL spectra. The PL analysis also reveals the excitation-dependent blue emission for all the synthesized samples, with the capping agent-processed samples exhibiting a less pronounced blue shift in the emission peak. The IV characteristics measured via four probe shows the semiconducting nature of the synthesized nanoparticles.
