Structural and Thermal Studies of ZnS and CdS Nanoparticles in Polymer Matrices

Structural and Thermal Studies of ZnS and CdS Nanoparticles in Polymer Matrices

We report the synthesis and structural studies of ZnS and CdS nanoparticles in polyvinylpyrrolidone (PVP), poly(vinyl alcohol) (PVA), and poly(methyl methacrylate) (PMMA) matrices. The metal sulfides/polymer nanocomposites were characterized by X-ray diffraction (XRD), Fourier transform infrared spe...
