“…The glass density increased linearly with increasing SrO content according to the formula ρ (x) = (0.0118 x + 2.3757) (g / cm 3 ) and R 2 = 0.991. The obtained value of the glass density for the composition x = 0 (2.3757 g/cm 3 ) is in good agreement with the experimental value obtained, which is equal to 2.32 g /cm 3 for the same glass composition as reported in [21].…”

“…The high modifier content in the glass was built of very short chains, such as Q 1 units and separated Q 0 units. The results of the depolymerization of the simulated glass by the strontium oxide modifier are in good agreement with those obtained experimentally for some similar composition of the network glass, which are confirmed by the infra-red (IR) and Raman spectra that show the role of the network modifier of Sr 2+ ions and also demonstrate that the structural network of these phosphate glasses comprises branching (Q 3 ), middle phosphate tetrahedra (Q ) and pyrophosphate (Q 1 ) and finally isolated entities (Q 0 ) [21].…”

“…Moreover, the introduction of SrO to phosphate glasses enhances their thermal stability and other physical properties. The incorporation of strontium as a network modifier cation (Sr 2+ ) disrupts the glassy network, which leads to the structure depolymerization and the creation of non-bridging oxygen atoms (Onb), and called terminal oxygen (OT) [3,4,21,22]. As reported in previous studies [23,24] that the numbers of non-bridging oxygens, also named terminal oxygen (OT), increase with more cation oxide content.…”

“…This effect may limit the potential applications for these glasses. The problem can be solved by the addition of alkaline earth such as strontium oxide (SrO), which very strongly increases the glasses' chemical durability [21]. Moreover, the introduction of SrO to phosphate glasses enhances their thermal stability and other physical properties.…”

Yttrium-ions-doped strontium phosphate-based glasses were prepared by following the classical melt quenching method. This study focuses on discovering the influence of the yttrium dopant on the physical, optical, and structural characteristics of synthesized glasses. The structural analyzes were performed using X-ray diffraction (XRD) and Fourier transformer infrared (FTIR). All of the examined samples exhibit an amorphous character, according to XRD. FTIR absorption spectra revealed that the phosphate network depolymerized, which increased with the level of Y 2 O 3 as the metaphosphate units decreased and the pyrophosphate species increased. The measured density values were used to evaluate the physical characteristics of the glasses samples. The density decreased from 2.108 to 2.099 g/cm 3 , while the molar volume values increased from 60.974 cm 3 /mol to 62.641 cm 3 /mol, when the yttrium concentration content increased from 0.0 mol. % to 1.5 mol. %. The optical measurement shows that the band gap for the energy values decreased from 6.528 to 5.754 eV, showing the alteration of the structure of strontium phosphate by an effect of the yttrium content. In addition, it was concluded that the refractive index of the samples rises with the yttrium oxide content and is inversely related to their optical band gap. Moreover, when the number of Y 3+ ions is increased, the electronic polarizability increases.The improvement of electronic polarizability gives a good medium for non-linear optical applications. The amount of Y 3+ ions present has a linear connection with the optical basicity of the materials studied. As a result, the studied glass materials could be useful in photonic applications.
