“…There are different types of glass such as silicate, phosphate, borate, and tellurite glass [3]. Tellurite glass has excellent properties and wide applications in optoelectronics, lasing material, sensing, and radiation shielding [4,5,6,7]. It has high refractive index, good thermal stability, good chemical and physical durability, low melting points, and low phonon energy [8,9].…”
