摘要:利用XPS测试方法对YAG:Ce3+荧光粉中的Ce3+含量进行了半定量分析,为研究Ce3+含量与YAG:Ce3+荧光粉发光强度的关系,在不同的烧结气氛下制备了一系列YAG:Ce3+荧光粉样品。通过分峰拟合计算可知,在4种不同的制备条件下,Ce3+的相对含量(fCe3+,用Ce3+峰面积与Ce3++Ce4+峰面积之比来估算)分别是88.46%,77.55%,75.33%和68.14%,所对应的烧结气氛依次为CO和N2的混合气氛、CO气氛、N2气氛和空气烧结气氛。YAG:Ce3+荧光粉的发光强度随着Ce3+相对含量的增加有显著增强。
XPS analysis is used to determine the percentage of Ce3+ in YAG.Ce3+ phosphor as a semi quantitative method. In order to confirm the relationship between the luminescence and the percentage of Cea+ more clearly, a series of YAG:Ce3+ phosphors were prepared under different sintering atmospheres. The results indicate that the relative percentages of Ce3+ (fee3+ , estimated as peak area of Ce3+ to Ce3+ + Ce4+ ) are 88.46%, 77.55%, 75.33% and 68.14%, respectively, corresponding to CO + N2 ,CO,N2 and air atmosphere by means of peak separation and fitting. The emission intensity of YAG. Ce3+ increased significantly with increasing Ce3+ concentration.
