Abstract: | LaBaB9O16 phosphors activated by various ions belonging to ns2, 3dn and 4fn configurations were prepared by combustion synthesis. Phosphors’ synthesis and luminescence spectra are reported. Most of the activators displayed intense characteristic emission. Pr3+→Gd3+, Ce3+→Tb3+, Ce3+→Dy3+, Ce3+→Mn2+ and Bi3+→Mn2+ energy transfers were also observed. In particular, Ce3+→Tb3+ energy transfer leads to an efficient green emitting phosphor. |
