Zirconium oxide (ZrO 2 ) nanoparticles have been prepared and examined by XRD. The transparent lead alkali borate glass systems of formula x ZrO 2 –20PbO 2 –(80 −  x )·Na 2 B 4 O 7 (0 ≤  x  ≤ 24 mol%) are prepared by melting quench method and doped by zirconia nanoparticles. Deconvolution of its FTIR reveals to increase the N 4 fraction boron atoms. This result reveals the Zr 4+ which forms BO 4 network units. The density and refractive index of chosen glass are increased due to add of ZrO 2 nanoparticles. Both ultrasonic velocities (longitudinal v L and shear v T ) increase with the ZrO 2 content increase. The packing density, bulk modulus and Young’s modulus increase with increasing of ZrO 2 nanoparticle content. The attenuation coefficients of the studied glasses have been measured at different energies (356, 662, 1173 and 1332 keV) using narrow beam transmission geometry. The obtained results indicated that, the values of the mass attenuation coefficient ( µ m ), the effective atomic number ( Z eff ) and effective electron density ( N el ) of the glass samples decreased with the increase in the ZrO 2 concentration at the energies (662,1173and 1332 keV), while these parameters ( µ m , Z eff and N el ) increased with the increase in the ZrO 2 concentration at 356 keV. The samples are irradiated 30 min by argon glow discharge plasma (GDP). The values of optical band gap decreased slowly with ZrO 2 nanoparticles increased and after plasma irradiation.
