Vacuum evaporated crystalline films of Zinc
Selenide (ZnSe) have been characterized by using optical spectroscopy
(especially absorption and transmission spectroscopy). Crystalline ZnSe
films have been deposited by vacuum evaporation technique on highly clean
glass substrates and their optical properties (energy band gap, refractive
index and extinction coefficient) have been studied. The energy band gap (Eg)
of the films has been calculated from absorption spectra by using Tauc
relation. The transmission spectra in the spectral range 400-850 nm has been
used to calculate the refractive index (n), extinction coefficient (k) and
wavelength dependence of n and k of the films have been studied. Optical
spectroscopy of the films have been done with the help of the Hitachi
spectrophotometer model U-3400.
