Abstract
Using a simple combustion process, rare earth doped novel compounds like fluorides LiBF<sub>4</sub> and Li<sub>3</sub>BF<sub>6</sub> can be prepared. Combustion synthesis furnishes a quick method for preparation of these phosphors. The prepared phosphors were characterized by the photoluminescence (PL) techniques. It is suggested that borofluoride based materials can be developed as low-cost phosphors. Formation of single phase compounds was confirmed by XRD. It is observed that prepared phosphors exhibited intense and characteristic Ce<sup>3+</sup> and Eu<sup>2+</sup> photoluminescence emission in blue visible region. This article summarizes fundamentals and possible applications of optically useful inorganic fluoride materials, with visible photoluminescence of Ce<sup>3+</sup> and Eu<sup>2+</sup> doped ions.
