Present work deals with Ga and In doped CdS nanocomposites by experimental and theoretical means. For theoretical simulations, we considered Supertetrahedron (Tn) cluster models of substitutionally and interstially (Ga, In) doped CdS. To mimic experimental conditions polyvinyl alcohol (PVA) chain fragments were allowed to cap the clusters. Structural and electronic properties have been calculated...
Nanocomposites of polyvinyl alcohol (PVA) with group III elements doped CdS have been synthesized via in situ chemical route. The optical properties of doped and pristine products are investigated by Raman spectroscopy, optical transmittance and photoluminescence (PL). Raman spectroscopy has shown peaks at 300cm −1 , 603cm −1 and 900cm −1 corresponding to first, second and...
