The new oxyborate phosphors, Na3La9O3(BO3)8:Eu3+ (NLBO:Eu) and Na3La9O3(BO3)8:Tb3+ (NLBO:Tb) were prepared by solid-state reactions. The photoluminescence characteristics under UV excitation were investigated. The dominated emission of Eu3+ corresponding to the electric dipole transition 5D0→7F2 is located at 613 nm and bright green luminescence of NLBO:Tb attributed to the transition 5D4→7F5 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 abstractThe dominated emission of NLBO:Eu located at 613 nm is from the electric dipole transition 5D0→7F2. NLBO:Tb emit bright green luminescence centered at 544 nm attributed to the transition 5D4→7F5. The concentration dependence of the emission intensity showed that the optimum doping concentration of Eu and Tb is 30% and 10%, respectively.Figure optionsDownload full-size imageDownload as PowerPoint slide
