| Abstract | ||
| Thin films of SnOz and SnOz:F have been prepared using SnCl2.2HzO with a new preparation conditions utilizing chernical spray-pyrolysis. 'lhe struciuril and optical properties have been studied for the as deposited thin films before and after irradiation by gamma rays. Bv XRD technique, it was found that the structuiebf the as deposited thin fihirs was polycrystalline, different peaks corresponds to (101), (200)' (211), with'a freferred orientation along (110) difection, the exposure of ihe as cieposlt6d ntms to a selected dosebf gamma rays, seems to decrease itthe intensity of these peaks and increase the full width at half maxima which leadi to an incrdasc in the average of grain size. Surface toDoeraDhv for the as depo-sited -films werc studied using a ,iiioriopl,'ii-*u', iound that radiation increase the structural delect and hence deireasc thc degree of crystallinir.v. | ||
