Tb³⁺-activated LTA zeolite-derived boro-aluminosilicate glass samples with a composition of xTb₂O₃-68(Na₂O-Al₂O₃-SiO₂)–32B₂O₃ (x = 0.2, 1.0 and 10 extra wt%) were prepared using the melt-quenching method. The emission spectra recorded upon ultraviolet (UV) excitation with two different wavelengths of 193 and 378 nm showed blue light (⁵D₃ to ⁷F_J=6,5,4 and ⁵D₄ to ⁷F₆ transitions of Tb³⁺) and green light (⁵D₄ to ⁷F₅ transition of Tb³⁺) emissions with comparable intensities up to a Tb³⁺ concentration of 10 extra wt%. Of note, the mean decay times of the green luminescence of the glass samples were relatively fast (<20 μs). The synthesized glass has potential in applications concerning UV imaging, UV detection, and plasma display panels.
