摘要：

The inorganic Oxy-borate host phosphors YCa4O(BO3)(3):RE3+ (RE = Eu3+, Tb3+) were synthesized by a novel solution combustion technique. The synthesis is based on the exothermic reaction between the fuel (Urea) and Oxidizer (Ammonium nitrate). The heat generated in reaction is use for auto combustion of precursors. The structures of the prepared samples were confirmed by powder XRD technique. The photoluminescence properties of the powder samples were investigated under UV and VUV excitation; "The phosphor YCa4O(BO3)(3): Eu3+ and YCa4O(BO3)(3):Tb3+ shows strong absorption in UV and VUV region and exhibits intense red and green emission upon excited by 254 nm UV and 147 nm VUV radiation''.
