摘要

The inorganic borate host phosphors YBO_3:REion (RE=Eu~(3+),Tb~(3+)) were synthesized by a novel solution combustion technique. The synthesis is based on the exothermic reaction between fuel (urea) and oxidizer (ammonium nitrate). The heat generated in the reaction was used for auto combustion of precursors. The photoluminescence properties and spectro-scopic investigation of the phosphor powder samples were investigated under ultraviolet (UV) and vacuum ultraviolet (VUV) excitation. The phosphors YBO_3:Eu~(3+) and YBO_3:Tb~(3+) show strong absorption in the UV and VUV region and exhibit intense orange-red and green emission, respectively, when excited by 254 nm UV and 147nm VUV radiation. The phosphor YBO_3 doped with Eu~(3+) and Tb~(3+) could be an efficient VUV-excited phosphor for plasma display phosphors (PDP) applications.
