%X The novel vacuum ultraviolet (VUV) excited Na3Y9O3(BO3)8:Tb3+(NYOB:Tb3+) green phosphor is prepared. Strong VUV photoluminescence and high quenching concentration of Tb3+ (20wt%) are observed in NYOB:Tb3+ and the strong emission are correlated with the unique layer-type structure of NYOB. All the characteristic 4f-5d transitions of Tb3+ and the host absorption band in VUV region are identified in the excitation spectrum. Based on the results, the energy levels scheme of Tb3+ in NYOB:Tb3+ is first established. This newly developed NYOB:Tb3+ phosphor shows excellent optical properties when compared with the commercial Zn2SiO4:Mn2+ and would be a potential VUV-excited green phosphor.
