Abstract: The selenium thin films of obliquely and normal deposited for different thickness were prepared using thermal evaporation method at pressure of 10<sup>- 5</sup>torr on to the glass substrate at room temperature. The band gap of thin films with respect to normal to vapour beam direction decreases with angle of deposition, which may be due to small increase in the thickness of the thin films with angle of deposition. The optical band gap has also been observed for different thin films having large variation in thickness.The optical energy band gap of these films decreases with thickness due to quantum size effect.
