摘要：

The melt-quenching method has been used to fabricate 9Na(2)O-(30-x) Bi2O3- xMoO(3)-40B(2)O(3)- 20SiO(2)-1Fe(2)O(3) glass system where x = (0 <= x <= 15 mol%). The XRD diffractometer procedure was used to check the status of these samples. Inter-ionic distance (R-i) between Mo-Mo, Polaron radius r(p), and inter-nuclear distance r(i) reduce with the Mo content due to reduce of molar volume. The two-photon absorption coefficient TPA increase with the increase of MoO3 this increased connected to E-g. The values of ionicity I-b slightly increase and the covalency of these glasses reduce with a growth in MoO3 content. The XRD patterns of glass-ceramic show (Na2B4O7), B2Si2O5, Na2SiO3, Fe7BSi3O18, and LiBi (MoO4)(2). The morphological of the glass-ceramic has been studied by SEM. FT-IR spectroscopic investigations of the glass-ceramic samples were applied to check the characteristic structure. Mass attenuation coefficient of the prepared samples decreased with the energy increase and with the addition of MoO3.
