1 mol% Eu₂O₃ + 1 mol% Tb₂O₃ + 4TiO₂ + 14ZnO + 20Na₂O + 60P₂O₅ co-doped glass has been synthesized by the melt quenching technique to investigate the optical and structural properties. The structural features are examined by XRD and FTIR spectra, and the spectroscopic properties are explored by absorption, excitation, emission, decay and CIE diagram. Upon excitation at 341 nm (Tb³⁺ band) luminescence emission transitions of both Tb³⁺ and Eu³⁺ are observed, however, for excitation at 393 nm (Eu³⁺ band), only Eu³⁺ emissions are noticed which indicate the evidence of energy transfer from Tb³⁺ to Eu³⁺ by non-radiative relaxation process. The decay profile of the glass follows double exponential function. The emission color of the sample characterized by the CIE chromaticity coordinates and CCT, are tuned by varying the excitation wavelength. The present glass could be utilized in W-LED for 341 nm excitation, display devices and photonics.

1 mol% Eu ₂ O ₃ + 1 mol% Tb ₂ O ₃ + 4TiO ₂ + 14ZnO + 20Na ₂ O + 60P ₂ O ₅共掺杂玻璃已通过熔融淬火技术合成，以研究其光学和结构特性。通过XRD和FTIR光谱检查结构特征，并通过吸收、激发、发射、衰变和CIE图探索光谱特性。在 341 nm（Tb ³⁺波段）激发时观察到Tb ³⁺和 Eu ^{3+ 的}发光发射跃迁，然而，对于 393 nm（Eu ³⁺波段）激发，只有 Eu ³⁺注意到发射，这表明能量通过非辐射弛豫过程从 Tb ³⁺转移到 Eu ³⁺的证据。玻璃的衰减曲线遵循双指数函数。通过改变激发波长来调整由 CIE 色度坐标和 CCT 表征的样品的发射颜色。本玻璃可用于 W-LED，用于 341 nm 激发、显示设备和光子学。
