dc.description.abstract The importance of this research comes from made a new material (Emulsion Definition) by used Gum Arabic and Black seed oil. The aim of this Research is Determine The optical properties of (Emulsion Definition) that made by used Gum Arabic Solution and black seed oil Such as (absorbance, transmission, reflection, absorption coefficient, extinction coefficient, refractive index and optical energy band gap) and to compare the result with pure gum Arabic solution result. In this research Four samples of (emulsifier) made by gum Arabic solution and black seed oil with different concentration (0.02, 0.03 ,0.04 and 0.05 ) mL was prepared and gum Arabic solution sample was reference .USB 2000 spectrometer was used to study optical properties (absorbance, transmission, reflection, absorption coefficient, excision coefficient and energy band gap).The absorption of all samples at wavelengths ranged (500- 800) nm, transmittance edge of all samples occurs at wavelength (675 nm) corresponding to photon energy (1.6 eV). The value of Energy band gap ( ) was decreased from (1.775) eV to (1.668) eV, the decreasing of ( ) Resulting from black seed oil molar increased on the samples. Which means that the addition of black seed oil improved the optical properties of the pure gum Arabic solution and thus expanded the fields of its use. en_US
