| Abstract | ||
| The research includes the study of the effect of the amount of ammonia (2, 5 and 8) ml on the optical properties of the membrane zinc sulfide (ZnS) nanoscale . Nanofilms attended using a chemical bath deposition method . The included optical properties: transmittance , absorbance , reflectivity , absorption coefficient , refractive index , extinction coefficient , the optical energy gap and the dielectric constant partially real and imaginary . It has been observed that increasing the amount of ammonia led to increased values of forbidden energy gap , has been prepared all models in concentration (0.05 M) and temperature (70 OC) and the time of deposition (30 min) where these conditions are optimal conditions for obtained on nanofilm by (CBD ) . It was to increase the amount of ammonia , clear effect on the thickness of the film were obtained on nanofilm in thickness (100nm) when the amount of ammonia (8ml). Was also noted that increase of ammonia may change clearly the rest of the optical properties. | ||
