摘要

@@ The novel vacuum ultraviolet (VUV) excited Nas Y9 O3 (BO3 )a: Tb3+ (NYOB:Tb3+ ) green phosphor is prepared.Strong VUV photoluminescence and high quenching concentration of Tb3+ (20 wt%) are observed in NYOB: Tba+and the strong emission are correlated with the unique layer-type structure of NYOB. All the characteristic 4 f - 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.
