中文摘要：
采用低温燃烧法合成SrMgAl10O17：Eu^2＋及SrMgAl10O17：Eu^2＋, Er^3＋蓝色发光材料,通过X射线衍射仪（XRD）、扫描电子显微镜（SEM）和荧光光谱仪（PL）等测试手段对所得样品进行表征. XRD及SEM测试结果表明：利用低温燃烧法合成SrMgAl10 O17材料具有较高的结晶度,且微量的稀土元素掺杂不会破坏其晶体结构；PL测试结果表明：SrMgAl10O17：Eu^2＋荧光粉在300-390 nm范围内可以被有效的激发,该波长范围与近紫外LED芯片匹配,发射光谱分布在430-520 nm之间,发射峰位于460 nm,属蓝光发射材料.共掺Er^3＋可显著增强SrMgAl10O17：Eu^2＋的发光强度,且当Er^3＋的掺杂浓度为4%时,样品的发光强度最大,较单掺Eu^2＋时样品的发光强度高出54.9%,表明Er^3＋对Eu^2＋的发光具有良好的敏化作用,该敏化作用的机理可以利用能量传递原理进行解释.
英文摘要：
The SrMgAl10O17：Eu^2＋ and SrMgAl10O17：Eu^2＋, Er^3＋ blue phosphors were synthesized by the combustion synthesis method. Their crystal structures and luminescent properties were analyzed by X-ray diffraction （XRD）、scanning electron microscope （SEM） and photoluminescence spectra, respectively. The XRD and SEM results indicate that the sample is well-crystallized in the combustion procedure, and its crystal structure has not changed when doped with low concentrations of rare-earth ions. PL results show that the phosphor of SrMgAl10O17：Eu^2＋can be effectively excited by near UV LED chip with a broad emission spectrum extending from 430 nm to 520 nm, and has main peaks located at 460nm. Furthermore, the sample of the luminous intensity is the largest when the Er2＋, Er^3＋co-doped concentration is 4%, and the emission intensity of Sr0.95MgAl10O17：0.05Eu^2＋, Er^3＋phosphor is significantly enhanced 54.9%higher than that of SrMgAl10O17：Eu^2＋phosphor. It is indicated that Er^3＋has good sensitization effect for Eu^2＋in luminescence, and this can be explained by the theory of energy transfer.
