Structural properties of ZnO films doped with Indium by chemical spray pyrolysis.

Abstract

Undoped Zinc Oxide and Indium doped Zinc Oxide with different doping
percentage (1,3,5,7)% by chemical spray pyrolysis have been deposited on
aglass substrate temperature (400
C) , The thickness of the prepared films
were (300±25) nm. The nature of Structure was examined by X-ray
diffraction technique. It was found that. The prepared undoped ZnO and In
doped ZnO have a hexagonal polycrystalline structure . With aprefered
Orientation along (101) for the undoped and In doped ZnO with doping
percentage (1,3)% . The preferred orientation was changed to be (002) for
the doping percentage (5,7)% . Also it was found that the average
crystallite size decrease as the increase in doping percentage (37.3 – 8.5)
nm. AFM images confirm that there is adifference in the nature of film
surfaces and the average grain size decrease with the increase of doping
percentage (104.57 – 87.99) nm . It was noticed there is avariation in nature
of film surface through the images of Scanning electron microscope . From
the EDS it has been identified.
