Blue Emission in Ce and Eu Activated Lithium Fluoro Borate Phosphors

چکیده
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 Ce and Eu photoluminescence emission in blue visible region. This article summarizes fundamentals and possible applications of optically useful inorganic fluoride materials, with visible photoluminescence of Ce and Eu doped ions.

A series of Ca1–xSrxS:Eu (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) phosphors were synthesized by solid-state reactions. The Ca1–xSrxS:Eu phosphors have a strong absorption at 455 nm, which corresponds to the emission wavelength of a blue LED. The emission peak of Ca1–xSrxS:Eu is blue shifted from 655 to 618 nm with increasing Sr content. The characteristics of Ca1–xSrxS:Eu phosphors make them suitable...
