| 摘 要： | 采用高温固相烧结法成功制备了Ba5-3x/2B4O11∶xEu3+(x=0.02~0.22)荧光粉,利用XRD和SEM等对荧光粉进行了结构和形貌表征。 在激发波长为393 nm的条件下,发射峰(596、621、657和706 nm)与Eu3+的5D0-7FJ(J=1,2,3,4)电子跃迁相对应,其中621 nm最强发射峰由Eu3+离子5D0→7F2电偶极跃迁造成。 文章还研究了Eu3+掺杂浓度对Ba5-3x/2B4O11∶xEu3+发光性能的影响,结果表明,荧光粉的发光强度随着Eu3+掺杂量的增加呈现先增大后减小的趋势,Eu3+最佳掺杂量为0.16。

| Abstract: | The phosphors, Ba5-3x/2B4O11∶xEu3+(x=0.02~0.22), were synthesized by high-temperature solid-state reaction method. The luminescence property of Ba5-3x/2B4O11∶xEu3+ was studied in this paper. The phase and surface topographies of as-prepared samples were characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM). This phosphor can be effectively excited at 393 nm and the emission peaks are located at 596 nm, 621 nm, 657 nm and 706 nm corresponding to the 5D0-7FJ(J=1,2,3,4) transition of Eu3+ ions, respectively. Therein the 5D0-7F2 electric dipole transition of Eu3+ ions, which locates at 621 nm, is the strongest wave crest. Investigation of Eu3+ content-dependent emission spectra indicates that x=0.16 is the optimum doping content of Eu3+ ions in the Ba5B4O11 host. |
