Microwave assisted radiant heating effect on the crystallization of SnO2 thin films prepared by spin-coating

Crystallization study of SnO2 thin films prepared by spin-coating method are reported when subjected to microwave assisted radiant heating (MARH). The as-prepared and annealed films are studied using atomic force microscopy, grazing incidence x-ray diffraction and conversion electron Mossbauer spectroscopy measurements. Sn4+ state in all films is confirmed from 119Sn Mossbauer spectroscopy measurements. The results indicate that one can employ microwave heating to prepare SnO2 thin films with controlled surface morphology which might be useful for various practical applications.
