| 摘 要： | 以粉煤灰为原料,采用固相法合成了Eu3+掺杂的铝硅酸钠发光材料。利用粉末X射线衍射仪(XRD)、扫描电子显微镜(SEM)、热分析技术(TG-DSC)、荧光光谱仪(PL)等对合成的样品进行表征,并与以分析纯的SiO2和Al2O3为原料得到的样品进行比较。结果表明:由不同的起始原料制备的NaAlSiO4:Eu3+均具有六方相结构;两种样品的形貌均不太规则,由许多小的球形颗粒和块状团聚体组成;由不同原料得到样品的TG-DSC曲线的变化趋势大致相同;在254及395 nm的紫外光激发下,均表现出Eu3+的特征发射。该研究为提高粉煤灰综合利用率、促进资源循环利用、减少其对环境的污染提供了一种新的思路。 |

| Abstract: | NaAlSiO4:Eu3+ phosphors were prepared by solid state method using coal fly ash as starting materials.The obtained samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),thermogravimetry-differential scanning calorimetry(TG-DSC),photoluminescence(PL) spectra,and compared with samples synthesized using analytical reagents SiO2 and Al2O3 as starting materials.The results indicated that NaAlSiO4: Eu3+ phosphors from the different starting materials had the same hexagonal phase.The morphology of these two samples was irregular and composed of small spherical particles and agglomerations.The TG-DSC curves were mainly similar to profile for the different samples.Under the excitation of 254 and 395 nm UV light,NaAlSiO4: Eu3+ phosphors exhibited characteristic emission of the doping Eu3+ ions.This investigation provided a good idea for improving the utilizing of resource and decreasing the pollution of coal fly ash to environment and soil. |
