  • Composition: 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, 10 wt%).
  • Emission spectra analysis upon UV excitation at 193 nm and 378 nm.

Main Results

  • Synthesized Tb<sup>3+</sup>-activated boro-aluminosilicate glasses.
  • Observed strong blue and green light emissions from Tb<sup>3+</sup> (<sup>5</sup>D<sub>3</sub>→<sup>7</sup>F<sub>J</sub> and <sup>5</sup>D<sub>4</sub>→<sup>7</sup>F<sub>J</sub> transitions).
  • Comparable emission intensities up to 10 wt% Tb<sup>3+</sup>; fast green luminescence decay times (<20 μs).
