Abstract:
The aim of this study is to compare structural and morphological properties of Sn doped ZnO films deposited by spray pyrolysis and chemical bath deposition. ZnO thin films, Sn doped or not, have been deposited by chemical bath deposition and spray pyrolysis. After deposition the films are annealed in room air, half an hour at 400°C. The films achieved are polycrystalline ZnO, with grains crystallized in the hexagonal structure. The films deposited par spray pyrolysis are homogeneous, their morphology does not vary strongly when Sn is introduced as dopant. In the case of chemical bath deposition the crystallite shapes depend significantly on the presence or not of Sn. Without Sn the grain of the films exhibit well resolved pyramidal geometry. With Sn, nanorods are clearly present in the films. This specific geometry depends on the Sn concentration. The presence of nanorods is explained by the possible catalyst effect of Sn during annealing at 400°C.
