| Abstract | ||
| An investigation which include synthesis of SnO2 thin film by depositing onto glass substrates at room temperature using thermal evaporation technique. The films were post-annealing in furnace tube at 250 oC temperature for different time (10, 20, 30 and 40 minutes). The films were characterized by AFM microscopy, FTIR and optical absorption spectrophotometer. The grain size was observed to increase with increase the annealing duration. Absorbance spectra were taken to examine the optical properties and band gap energy was observed to decrease with increase the annealing duration. The effect of annealing time on the optical and morphological properties of films were studied and discussed | ||
