Zinc antimony borophosphate glasses has been determined for [10P2O5 –40B2O3 –xSb2O3 –(50–x)ZnO] and composition of [10P2O5 – 40B2O3 –40Sb2O3 –10ZnO] has been doped with 1 mol% of rare earth (Eu, Nd, Sm, Er). The functions of compositional changes on their structural features were examined using X–Ray Diffraction (XRD) to detect the amorphousity phase present. While Fourier Transform Infrared (IR) Spectroscopy were used to identify the presences of vibrational modes and band assignments of phosphate, borate, antimony, zinc and Rare earth ion in the system. XRD results expose that crystalline phase changes with different amount of zinc and antimony substitution. Hydroxyl group absorption also vary due to this composition changes and clearly shown in IR spectroscopy in the ranges 1400–4000 cm–1. Result of IR spectroscopy indicated that bands around 1440 cm–1 and 760 cm–1 was ascribed to the vas(B–O–B) and vs(P–O–P) vibration respectively. The changes of this vibration indicated that P–O–B linkage was formed near 660 cm–1. The modification of zinc antimony borophosphate glasses with rare earth was studied and showed present of rare earth ion in the glass system does not change the structural features.References
