Abstract
Transparent conductive thin films of nanocrystalline Sb:SnO 2 have been deposited onto preheated glass substrates by using spray pyrolysis technique. The effect of the solution molarity on structural, morphological, optoelectronic properties of Sb:SnO 2 films has been investigated. XRD study reveals that films are polycrystalline with tetragonal crystal structure having average crystallite size about 20 nm. The compact and homogeneous grains are seen in FESEM images. The BEs of Sn 3d 5/2 for all samples show the Sn 4+ bonding state for SnO 2. The BEs of Sb 3d 5/2 are in the range of 530.6–530.9 eV, indicating that all antimony detected is in a pentavalent state (Sb 5+). Transparency of films in the visible region decreases with increase in precursor concentration. Photoluminescence study shows the strong violet and weak orange emission. The sensing properties of the Sb:SnO 2 films for acetone, ethanol and LPG with operating temperature and gas concentration have been investigated.
