Tin oxide /Metal sulfide nanocomposites were synthesized using two step solution route. In the first step SnO2 gel were obtained followed by the next step of addition of precursor of cadmium and sulfide salts. Films were grown on cellulose flexible substrate using spin coating method. All the samples were analyzed using structural, morphological and optical characterizations. In X ray diffractograms, tetragonal rutile structure is observed with shift in peak towards lower angle due to tensile strain. SEM micrographs show that the ring like structure converted into flake like structures. AFM micrographs also confirm the ring like or porous film converted into flake. Photoluminescence spectra exhibits the intensity of SnO2-CdS decreases as compared to SnO2. Optical transmittance confirms the formation of nanocomposite due to additional band was observed in nanocomposites.
