| 摘 要： | 采用固相合成法制备了钡铝酸盐绿色荧光粉xBaO·6Al2O3∶Mnz,研究了化学组成对晶体结构、VUV发光性能的影响。当0.7≤x≤1.5,随着Ba2+的增加存在BaAl13.2O20.8→BaAl12O19→BaAl9.2O14.8的基质结构转化。Ba2+含量较低时,存在与基质晶格共晶的BaMnAl10O17结构,并且随着Mn2+含量的增加BaMnAl10O17结构的数量增加。Ba2+含量对VUV激发光谱谱形有较大影响;Mn2+含量增加使发射光谱略有增宽。当Ba2+、Mn2+的含量分别为x=1.0与z=0.10～0.12时,具有最优的发光效率。 |

| Abstract: | xBaO·6Al2O3∶Mnz phosphors were synthesized by solid state reaction method, their crystal structures and luminescent properties under VUV excitation were investigated. Crystal structure transformation of BaAl13.2O20.8→ BaAl12O19→BaAl9.2O14.8 appears in the host matrix with increasing Ba2+ content while 0.7≤x≤1.5. BaMnAl10O17 cocrystallized with Ba-poor hexaaluminates is detected by XRD and its amount increases with Mn2+ increasing. VUV excitation spectrum is affected by the concentration of Ba2+, while the emission linewidth depends on the Mn2+ concentration. The maximum luminance is obtained at x=1.0 and z = 0.10～0.12. |
