| Summary: | Tb<sup>3+</sup>-activated LTA zeolite-derived boro-aluminosilicate glass samples with a composition of xTb<sub>2</sub>O<sub>3</sub>-68(Na<sub>2</sub>O-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub>)–32B<sub>2</sub>O<sub>3</sub> (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 (<sup>5</sup>D<sub>3</sub> to <sup>7</sup>F<sub>J=6,5,4</sub> and <sup>5</sup>D<sub>4</sub> to <sup>7</sup>F<sub>6</sub> transitions of Tb<sup>3+</sup>) and green light (<sup>5</sup>D<sub>4</sub> to <sup>7</sup>F<sub>5</sub> transition of Tb<sup>3+</sup>) emissions with comparable intensities up to a Tb<sup>3+</sup> 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.
