| 摘 要： | 采用sol-gel法制备CaSnO3:Eu3+荧光粉。研究了在制备过程中添加表面活性剂聚乙二醇(PEG10000)对CaSnO3:Eu3+结构、粒度、形貌及发光性能的影响。通过X射线衍射(XRD)、激光粒度仪,扫描电镜(SEM)及荧光分光光度计对样品进行了表征。结果表明:在制备过程中添加PEG没有改变样品的结构,很好地改善样品粒度以及形貌,荧光粉的相对发光强度也稍有增强。

| Abstract: | The red phosphor of CaSnO3 ∶ Eu3+ powders were prepared by sol-gel method. During the preparation, PEG (10000) as is the surfactant was added in CaSnO3 ∶ Eu3+phosphor. The influence of PEG(10000) on crystal structure, particle size, morphology and luminescent properties of the phosphor were investigated by means of X-ray diffraction (XRD), laser particle size analyzer, scanning electron microscopy (SEM) and the fluorescence spectrophotometer. The results showed that the structure of CaSnO3 ∶ Eu3+ is not changed by PEG (10000) adding, in the same time the particle size and the morphology were improved by the disperse effect of PEG(10000). And the luminescent intensity of CaSnO3 ∶ Eu3+is enhanced slightly only by adding the PEG(10000). |
