Abstract Scope |
Zinc oxide is a very important material (ZnO) of diverse uses in solar cells, optoelectronic devices, and other applications. Optimizing the optical properties is required in such applications. In this work the influence of annealing in nitrogen atmosphere and aluminum doping on the optical properties was investigated. undoped (ZnO) and aluminum doped (ZnO:Al) thin films were deposited using spray pyrolysis (SP) method on glass substrates. The microstructure of the films was explored using X-ray diffraction and the films are polycrystalline. Transmittance of the films was recorded as a function of wavelength in the range 300-1100 nm. Transmittance was used to calculate absorption coefficient, extinction coefficient, reflectance, refractive index, real and imaginary parts of the dielectric constan, and optical conductivity. All these parameters are found to be affected by Al-doping and annealing. |
