<br/><br/>Thesis (Ph.D.) - Cairo University - Faculty of Science - Department of Physics 
<br/><br/> This thesis includes the investigation of P₂O₅ZnONa₂O glasses doped with various concentrations of NiO in the range from 1 to 6 mol %.The prepared samples were subjected to different tests such as X-ray diffraction, UV-VIS spectrophotometer, Fourier transform infrared spectroscopy (FTIR) and ac conductivity. From these measurements found that all composites have optical filter behavior in the VIS and IR regions, also they show grate dielectric properties which make it can be used in wide industry applications. All data were analyzed in terms of current theories
