Green- and Blue-Emitting Tb³⁺-Activated Linde Type A Zeolite-Derived Boro-Aluminosilicate Glass for Deep UV Detection/Imaging

Tb3+-activated LTA zeolite-derived boro-aluminosilicate glass samples with a composition of xTb(2)O(3)-68(Na2O-Al2O3-SiO2)-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 (D-5(3) to F-7(J=6,5,4) and D-5(4) to F-7(6) transitions of Tb3+) and green light (D-5(4) to F-7(5) 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 mu s). The synthesized glass has potential in applications concerning UV imaging, UV detection, and plasma display panels.
