The surface and volume energy loss of Safranin O thin film prepared by spin coating method

Hassan K. Ibrahim


Optical properties of safranin O doped polyvinyle pyrolidone (PVP) thin film prepared by spin coating method on glass substrate at room temperature was investigated .The analysis of the absorption data revealed existence of indirect transition in the optical band gap. The optical constants such as absorbance, transmission, reflection, refractive index, extinction coefficient, real and imaginary parts of dielectric constants, optical and electrical conductivity, dispersion energy Ed and oscillation energy E0 and the surface, volume energy loss function and electronic interband transition strength have been investigated at film thickness 10 mm over spectral of (300-800) nm.

Keywords: Polymer, Energy gap, Optical constant
