Title: Photoluminescence properties of a novel phosphor, Na{sub 3}La{sub 9}O{sub 3}(BO{sub 3}){sub 8}:RE {sup 3+}(RE=Eu,Tb)

Abstract

The new oxyborate phosphors, Na{sub 3}La{sub 9}O{sub 3}(BO{sub 3}){sub 8}:Eu{sup 3+} (NLBO:Eu) and Na{sub 3}La{sub 9}O{sub 3}(BO{sub 3}){sub 8}:Tb{sup 3+} (NLBO:Tb) were prepared by solid-state reactions. The photoluminescence characteristics under UV excitation were investigated. The dominated emission of Eu{sup 3+} corresponding to the electric dipole transition {sup 5} D {sub 0}{sup {yields}}{sup 7} F {sub 2} is located at 613 nm and bright green luminescence of NLBO:Tb attributed to the transition {sup 5} D {sub 4}{sup {yields}}{sup 7} F {sub 5} is centered at 544 nm. The concentration dependence of the emission intensity showed that the optimum doping concentration of Eu and Tb is 30% and 10%, respectively. - Graphical abstract: The dominated emission of NLBO:Eu located at 613 nm is from the electric dipole transition {sup 5} D {sub 0}{sup {yields}}{sup 7} F {sub 2}.
