摘要
将一种经可见光激发后能储藏能量、其余辉时间较长的长余辉荧光粉加入聚甲基丙烯酸甲酯(PMMA)透明塑料中,制成光致发光材料。测定了荧光粉的吸收和发射光谱,并研究了荧光粉的加入对PMMA的发光强度、透光性能、流动性能、动态力学性能、拉伸强度、表面硬度、吸水性能等的影响。结果表明,经过适当的控制,可获得性能较好的光致发光聚甲基丙烯酸甲酯塑料。
A kind of plastics with long persistent fluorescence that could be activated by visible light was prepared by adding some fluorescent powder into common PMMA plastics.The absorbing and emitting spectra of the fluorescent powder were determined.The effects of the fluorescent powder on the luminous intensity,transmissity,rheological properties,mechanical properties,tensile strength,surface hardness and water absorption of the plastics were studied.The results showed a fluorescent PMMA plastics could be prepared by means of proper controlling.
