Optical Properties of ZnTe Thin Films Prepared By Chemical Spray Pyrolysis
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.Thespectral dependences of absorption coefficient were calculated from transmissionspectra. The allowed direct and optical band gap energy has...

| description | 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.Thespectral dependences of absorption coefficient were calculated from transmissionspectra. 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)andrefractive index (n) have been evaluated. |
