Nanostructured SnO2 thin films were deposited on glass substrate using chemical spray pyrolysis technique. Three influent synthesis parameters, namely (i) the precursor concentration (0.2M and 0.5M), (ii) the substrate temperature (250°C and 350°C) and (iii) doping with zinc (Zn) were investigated in term of their effects on the morphology and structure of SnO2 thin films. These films were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectrometry (EDX) techniques. The grain size of the films was observed to increase as the concentration of the precursors is increased. Substrate temperature is proved to be crucial in determining the crystallinity of the films as the films are reported to grow at temperature above 270°C. Besides, the addition of dopant was found to reduce the grain size of the film.
