Abstract

In this article, the capping action of Sodium carboxymethyl cellulose (NaCMC) on ZnS nanoparticles synthesized by microwave-assisted method is reported. The X-ray difraction and electron difraction studies corroborated nanocrystalline nature of cubic ZnS. Discontinuous cluster growth of particles was implied by optical absorption studies. This was refected in transmission electron microscope images. Fourier-transform infrared studies confrmed NaCMC capping on the surface of ZnS nanoparticles. Efective encapsulation of ZnS nanoparticles by NaCMC was further supported by Raman scattering, thermal studies and photoluminescence studies. Surface modifcation of ZnS nanoparticles with NaCMC appear to be suitable for specifc biomedical applications due to the nontoxicity of ZnS and NaCMC.
