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