Tailoring of Optical, Dielectric, and Structural Parameters of PVA by CdS-Ag Core-Shell Nanoparticles and UV Irradiation

Aditi Nain, Rishi Pal Chahal, Ekta Dhanda, Sanjay Dahiya

Abstract

Chemical reduction process was employed for formation of CdS-Ag CSNs. Consequently, different weight % of these core shells were embedded in PVA. Further, these films were exposed with UV radiation and changes in optical, structural and dielectric parameters were observed. XRD and TEM was done to establish formation of CSNs. By evaluation of UV–vis data band gap of PVA was observed to reduce after embedding CSNs and linear and non-linear optical parameters like n0, χ[1], χ[3], n2 were discussed corresponding to weight % and UV exposure. Effect of weight % of CSNs and UV on structure, ac conductivity and dielectric parameters is discussed in detail.
