采用静电纺丝法制备MgO,SiO2,Nd2O3,MnCO3与PVA膜混合物,再通过高温固相法制备长余辉发光材料MgSiO3∶Mn2+,Nd3+,对这种红色长余辉材料的发光性能进行了研究。借助SEM对其表面形态进行表征,激发光谱、发射光谱和余辉衰减曲线表征样品的发光性能。研究发现,PVA及纺丝工艺没有对MgSiO3∶Mn2+,Nd3+样品的晶体结构造成破坏,样品发射峰型没有变化,相对可见光样品对紫外光的吸收更好。采用静电纺丝法制备的发光材料与高温固相法制备的发光材料相比其发光性能及粒径都有一定程度的改善。
The luminescent properties of long-lasting luminescent material MgSiO3: Mn2 +, Nd3 + were prepared by electrospinning method and the mixture of MgO, SiO2, Nd2O3, MnCO3 and PVA was prepared by high temperature solid-state reaction. The morphology of the surface was characterized by SEM, and the luminescence properties of the samples were characterized by excitation, emission and afterglow decay curves. The results show that the crystal structure of MgSiO3: Mn2 + and Nd3 + samples is not damaged by PVA and spinning process, and the peak shape of the sample does not change, and the relative visible light samples absorb better UV light. The luminescent materials prepared by the electrospinning method and the luminescent materials prepared by the high temperature solid phase method all have a certain degree of improvement compared with the luminescent materials.
