SPECTROSCOPIC STUDIES OF (PMMA- CD (NO3)2 .4H2O) COMPOSITES

Composistes consisting of an poly (methyl methacrylate) matrix and Cd(NO4)2.4H2O as filler are designed. The optical properties were measured in the wavelength range from (190-850) nm. The experimental results showed that the absorption coefficient, extinction coefficient, refractive index and real imaginary parts of dielectric constants are increasing with increase the addition of Cd(NO4)2.4 H2O content.
