A novel phosphate-based glass system was fabricated to be applied in some dental applications. The fabricated glass system consists of non-toxic CaO–K₂O–Na₂O– P₂O₅ compounds and described by the chemical formula (40 + x) P₂O₅+20CaO+(30-x) Na₂O+10K₂O, where 0 = x ≤ 20 mol%. The absorption spectra of the fabricated glasses were recorded by the UV–Vis spectrophotometer in the wavelength range 200–1100 nm. The refractive index found to be decreased from 2.438 to 2.328, while the direct energy gap was enhanced from 3.626 to 3.880 eV with increasing the P₂O₅ concentration. Moreover, the fabricated glass system's gamma-ray shielding capacity was examined using the Geant 4 simulation code, and compared with the NIST photon cross-section database (XCOM) in the energy region between 0.161 and 2.51 MeV. The highest linear attenuation coefficient (LAC) was obtained for glass samples with 40 mol% of P₂O₅, varied between 0.326 and 0.091 cm⁻¹. In contrast, the lowest LAC was achieved for glass samples with 60 mol% of the P₂O₅ compounds, decreased from 0.301 to 0.087 cm⁻¹ when the gamma photon energy was raised from 0.161 to 2.51 MeV, respectively.

制造了一种新型磷酸盐玻璃系统，用于某些牙科应用。制造的玻璃系统由无毒的 CaO–K ₂ O–Na ₂ O– P ₂ O ₅化合物组成，化学式为 (40 + x) P ₂ O ₅ +20CaO+(30-x) Na ₂ O+ 10K ₂ O，其中 0 = x ≤ 20 mol%。用紫外-可见分光光度计在 200-1100 nm 波长范围内记录所制造玻璃的吸收光谱。发现折射率从 2.438 降低到 2.328，而直接能隙随着 P ₂ O _{5 的}增加从 3.626 增加到 3.880 eV专注。此外，使用 Geant 4 模拟代码检查制造的玻璃系统的伽马射线屏蔽能力，并在 0.161 和 2.51 MeV 之间的能量区域与 NIST 光子截面数据库 (XCOM) 进行比较。对于具有 40 mol% P ₂ O _{5 的}玻璃样品，获得最高线性衰减系数 (LAC) ，在 0.326 和 0.091 cm ^-1之间变化。相比之下，当伽马光子能量从 0.161 提高到 2.51 MeV 时，具有 60 mol% P ₂ O ₅化合物的玻璃样品的 LAC 达到最低，从 0.301 降低到 0.087 cm ^-1。
