| Abstract | ||
| Thin films of ZnTe have been prepared by the method of chemical spray pyrolysis .The absorption and transmissions spectra are recorded in the range 400-900nm.The spectral dependences of absorption coefficient were calculated from transmission spectra. The allowed direct and optical band gap energy has been evaluated from (αhν)2 vs. (hν) plots. The optical constants such as extinction coefficient(k)and refractive index (n) have been evaluated. | ||
