Structural and optical characterization of CdS/TiO2 nanocomposite

► Advantage of CdS/TiO2 over TiO2 prepared via Co-precipitation method. ► Appearance of positive slope has ensured the presence of tensile strain. ► New Raman bands for rutile TiO2 which has not been previously reported. ► Activation of the excited TiO2 in the presence of CdS rather than deactivation.
