A mixture of an aqueous solution of thiourea, tin chloride dehydrate and copper chloride was used as spraying liquid. The optimum volumetric ratio of mixing was found to be [S/(Cu+Sn)=1] at pH =1.5, in the present work. XRD examination revealed CTS in a monoclinic phase.A number of platform speeds were employed in the spraying process. XRD peaks were described at 2θ = 28.39°, 33.02°, 47.34°, and 56.39° corresponding to , , , and , respectively. The FTIR investigations certified a numeral of the chemical bond of Cu-, Sn- and S-. The crystallite size was observed in the range of nano-sized using Scherrer formula. Studying surface morphology of CTS films reveals a uniform coating on the substrates which approved by SEM investigations.
