The present work aims to fabricate of chitosan doped with SnO2-ZnO nanoparticles to employ in various optical and electronics applications. The study included the compact of (SnO2/ZnO) nanocomposites on optical features of chitosan to be used in variety of optics and electronics applications. The chitosan-SnO2/ZnO nanocomposites have been prepared by utilizing casting technique with various concentrations of (SnO2/ZnO) nanoparticles and chitosan. The optical features have been investigated at a range of wavelengths from (320 - 920 nm). The analysis reveal that when (SnO2/ZnO) nanoparticles ratio has been increased, absorption value of chitosan-(SnO2/ZnO) nanocomposites was boosted whereas the transmittance value was drop down. Whenever (SnO2/ZnO) nanocomposites ratio have been rise, the band gap was reduced from 3.33 to 2.9 eV for allowed transition and from 3.13 to 2.51 eV for forbidden transition. The other optical features of chitosan-SnO2/ZnO nanocomposites have been boosted. Finally, the outcomes of optical features reveal that the chitosan-SnO2/ZnO nanocomposites are being possible to be utilized in a variety of applications.
