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