In this study, nanoparticles of neodymium oxide were deposited on NaX zeolite powder using a 5.3 kJ Mather-type plasma focus device. The NaX zeolite samples were exposed to the 10, 15, and 20 shot numbers of the plasma focus device at a distance of 14 cm from the anode tip and 0 angular positions with respect to the anode axis. Parent NaX zeolite and NaX:Nd composites with different Nd 2 O 3 percent weights were characterized using different techniques such as; XRF, XRD, SEM, FT-IR, and UV-vis. It was shown that the amount of Nd 2 O 3 in the samples increases with increase of the shot number. It was also found from the results that variations in amount of Nd 2 O 3 can have signi cant effects on the degree of the crystallinity and optical properties of nal products such as refractive index, band gap energy, dielectric constant, and absorption coe cients.
