الملخص EN

In this research we have prepared nanocomposite material based on polymeric material which it Poly methyl meth acrylate (PMMA) and doped by Copper Nanoparticles (Cu) with different weight percentages (5wt%,10wt%) .

The absorption and transmission spectra has been recorded in the wavelength range (200-1100)nm, the absorption coefficient and energy gap of the indirect ,allowed,forbidden transition have been determined.
