| Abstract | ||
| Thin film of a dye(p-Naphtholbenzein( ))was prepared by spin-coating technique on glass.The optical properties of the P-Naphtholbenzein( )(with thickness )were investigated at room temperature and they include absorbance/transmittance/reflectance, spectra, absorption coefficient ,extinction coefficient ,optical conductivity and complex dielectric constant.The data of absorption coefficient indicated for direct transition with direct energy gap (Eg ).We have also studied Ubrach energy and the ratio of carrier concentration to the effective mass ( N/m* ) . | ||
