ABSTRACT Using a simple combustion process, rare earth doped novel compounds like fluorides LiBF4 and Li3BF6 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 Ce3+ and Eu2+ photoluminescence emission in blue visible region. This article summarizes fundamentals and possible applications of optically useful inorganic fluoride materials, with visible photoluminescence of Ce3+ and Eu2+ doped ions.
