| 摘 要： | The novel vacuum ultraviolet （VUV） excited Na3 Y9O3 （BO3）8：Tb^3＋ （NYOB：Tb^3＋） green phosphor is prepared. Strong VUV photoluminescence and high quenching concentration of Tb^3＋ （20 wt%） are observed in NYOB： Tb^3＋ and the strong emission are correlated with the unique layer-type structure of NYOB. All the characteristic 4 f - 5d transitions of Tb^3＋ and the host absorption band in VUV region are identified in the excitation spectrum. Based on the results, the energy levels scheme of Tb^3＋ in NYOB：Tb^3＋ is first established. This newly developed NYOB：Tb^3＋ phosphor shows excellent optical properties when compared with the commercial Zn2SiO4：Mn^2＋ and would be a potential VUV-excited green phosphor.

| Abstract: | 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. |
