【摘要】 通过溶胶-凝胶技术制备了以稀土离子Eu³⁺为激活剂的硅基发光材料,并通过Na₂WO₄的掺杂考察了其对体系发光性能的影响。主要研究了三维荧光光谱,荧光激发光谱和发射光谱,分析探讨了Na₂WO₄的掺入对发光中心Eu³⁺发光性质的影响,并通过能级图、位形坐标图和敏化过程示意图等理论结合图对这个影响的原因进行了进一步的说明和探讨。更多还原

【Abstract】 Eu³⁺ doped silica materials were prepared by sol-gel method and the effects of luminescence properties when doping Na₂WO₄ to the system were investigated.The luminescence properties of the material were measured by the three dimensional spectra, emission spectrum and excitation spectrum.The energy transfer during the activator and WO₄^2- ion were explained by level chart,configuration coordinate diagram and diagram of sensitization effect.更多还原
