Abstract:

Al_xYB₂O₃ [(6-x–Y)P₂O₅]TeO₃ (x = 3, 2, 1, and Y = 2.5, 1.5, and 0.5) was synthesised by the sol–gel autocombustion method and calcinated at 800 °C for 2 h. The ultraviolet–visible study shows maximum absorbance at ~ 264 nm with optical band gaps ranging from 4.21 to 4.24 eV. The X-ray diffraction pattern confirmed the body-centred cubic (BCC) structure, with an average particle size of 21.63–25.77 nm. The glass nanomaterials have a total composition appearance; their granular morphological shape was confirmed by field emission scanning electron microscopy and energy-dispersive X-ray spectroscopy (FE-SEM and EDS); and their porous nanorods were exhibited by high-resolution transmission electron microscopy (HR-TEM). The incorporation of TeO₃ units into the glass network is associated with the depolymerisation of borophosphate chains influenced by aluminium, as revealed by the Raman spectra. The glass nanomaterial acts as a conducting material because of its dielectric loss. As well, the application of the various antimicrobial and anticancer activities for compound concentrations (x = 1 and Y = 0.5) is strongly inhibiting the growth of the human cervical cancer cell line HeLa.
