Determination of Optical and Structural Properties for a Semiconductor Marital Manufactured from Gum Arabic Doping by Iodine

Abstract

In this work, Gum Arabic (Talha and Hashaba) Nano-material samples were prepared with different Concentration (0.1, 0.3, 0.5, 0.7 and 0.9) m Molar by doping with Iodine. Optical Properties of Gum Arabic doping by Different Concentration of Iodine measured by using the UV- Spectroscopy min 1240, The Nano crystal size of all samples was measured by XRD technique, and study effect of different concentrations on the particle Size and crystal properties of all samples. The study the effected of different concentration on the optical parameters. For all samples the absorbance increases upon increasing the concentration, while the transmission decreases. The value of Energy band gap (Eg) decreased from (4.420) eV to (4.323) eV. The density increasing by rated 0.5465 mg. Cm-3/molar. Particle Size decreasing by rated 2.41 nm / molar, and d-spacing were decrease molar rated 10-10m / molar. And for FTIR there are found all this band (metal-oxygen vibration at difference positions is due to the different values of metal ion-O􀬿􀬶 , C-C stretch and CC- H bending, O-H bending vibration , C=C stretching and stretching mode of H-O-H bending vibration of free or absorbed water which implies that the hydroxyl groups are retained in ferrites in all samples of Gum Arabic (Talha and Hashaba
