| 摘 要： | 以强碱性阴离子交换树脂为沉淀剂,采用离子交换法制备了ZrO_2:Eu~(3+)纳米晶,通过XRD,TEM,HRTEM和EDS等对晶体的结构、形貌及化学成分进行了表征,利用3D荧光光谱、激发光谱和发射光谱研究了Eu~(3+)在ZrO_2纳米晶中的发光性质。结果表明,焙烧温度在800℃以下所得的ZrO_2:Eu~(3+)纳米晶主要为四方结构,晶粒尺寸约为5—20 nm,随着焙烧温度的升高,样品的晶结构发生了细微变化,从900℃开始出现了少量单斜晶,由ZrO_2:Eu~(3+)的3D荧光光谱确定了其最佳监测波长和发射波长,在394 nm波长光的激发下观察到纳米ZrO_2中Eu~(3+)的590 nm(~5D_0→~7F_1)和606 nm(~5D_0→~7F_2)特征发射谱,随着相结构细微的变化,发射光谱的形状及强度均发生变化,说明ZrO_2:Eu~(3+)纳米晶的发光性质对其结构非常敏感。

| Abstract: | Eu~(3+) doped luminescent nano-materials have become a research focus due to their outstanding physical and chemical properties in light-emitting,magnetism,thermology,catalysis and chemical activity etc..Furthermore,the relationship between crystal structure and energy levels transition of these nano materials can be easily obtained by measuring the spectra of doped Eu~(3+).Among luminescence nano materials,ZrO_2 nano-crystal as a potential one has been attracted great attention in its higher refractive,goo... |
