Abstract:
Silver Nanoparticle materials had been synthesized to produce new alternate substance for reducing the rare or high cost of industrial materials. In this work, three samples of silver nitrate were prepared with different concentrations (0.04, 0.05 and 0.06) molar by chemical method, and effect with gamma ray on the all sample that mead , the add to the bacteria. The optical absorbance properties were investigated for all sample that made by used the ultraviolet-visible (UV-Vis) spectroscopies. The maximal optical absorbance equal 1.44 a.u for sample (Ag Nano 0.04 Molar +R) at 200 nm wavelength , minimal value 0.705 au for sample (Ag Nano 0.06 ) at the same wavelength ,but when add bacteria equal 0.812 a.u at 213 nm for the ( Ag Nano 0.06 Molar +R) sample . The optical energy band gap value of were decreasing from 5.618 eV to 5.227 eV by increasing the molar and effect by gamma ray.
