Abstract

In this work, the optical properties of (CMC/PVA/ Mg- Chlorophyll) nanocomposites films prepared by casting method have studied to use in different optical fields. The Mg-Chlorophyll added with different weight percentages are (2,4,6 and 8) wt% (CMC/PVA/Mg-Chlorophyll). The results revealed that absorbance, absorption coefficient, extinction coefficient, and refractive index of the optical characteristics of nanocomposites for wavelength range (200-1100) nm. all with rising content of Mg-Chlorophyll. while the energy band gap and transmittance decreased with increasing concentration of Mg-Chlorophyll.Optical energy values gap from (4.8 – 2.8) eV, where the optical energy gap of produced films reduced as concentration of Mg-Chlorophyll increased.while the energy band gap and transmittance decreased with increasing concentration of Mg-Chlorophyll.Optical energy values gap from (4.8 – 2.8) eV, where the optical energy gap of produced films reduced as concentration of Mg-Chlorophyll increased.while the energy band gap and transmittance decreased with increasing concentration of Mg-Chlorophyll.Optical energy values gap from (4.8 – 2.8) eV, where the optical energy gap of produced films reduced as concentration of Mg-Chlorophyll increased.
