Effect of Li+ ions on structural, optical and nano-crystallization behaviour of Na2O-CaO- P2O5-B2O3 glass system: Biomedical applications
Source abstract
Abstract
Glassy system of composition xLi 2O.3P 2O 5.21Na 2O.26CaO.(50- x)B 2O 3 ( x = 0, 1, 2, 3 and 4 mol%) was prepared by melt quench technique. X-ray diffraction, Infrared spectroscopy and Field emission scanning electron microscope with Energy dispersive spectroscopy were conducted to identify crystalline phase formation in glass powder and to study morphologies. The deconvoluted IR absorption spectra of synthesized samples, were analyzed to examine the structural rearrangements in the glass matrix before and after immersing in the phosphate solution. Optical band gap, Urbach energy and refractive index of the synthesized compositions were also obtained from the analysis of optical absorption spectra to examine the semiconducting behavior. The effects of the treatment in phosphate buffer solution for 12 days on crystallization & structural properties of these glasses were systematically investigated. The dependence of physical parameters on the glass composition suggested a variation in the number of non-bridging oxygen with Li 2 O content. Morphological and structural study alongside a possibility of hydroxyapatite formation suggests the biomedical applications of these materials.
