Mn doped ZnO films were prepared by SILAR technique. These films were characterized by hardness study and Scanning Electron Microscope. The undoped ZnO film hardness decreased. The Mn atoms occupy the intersistial position. Due to this reason hardness were increased by heating. During the annealing the atoms were oriented in different direction. Based on the orientation it appeared as various morphologies (needle and Hone cone structure).
