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.

Keywords:	Rare earth compounds Photoluminescence Combustion synthesis Borate
