摘　　要：长余辉材料,一般是指材料在受到光的照射后,撤去激发源后,材料能够保持较长时间的发光的一类材料。古代的夜明珠和现在有些提示标牌,荧光棒等都含有长余辉材料。现在的长余辉材料的发展经历了硫化物到铝酸盐的发展过程。其中,稀土掺杂铝酸锶材料余辉时间长,亮度比较好,化学和热性能比较稳定,对环境友好无毒,已经逐步代替硫化物长余辉材料,在蓝光到绿光发光的长余辉发光领域广泛应用。目前长余辉材料已经广泛应用于标识标牌,开关标识,夜光涂料等方面,在交通、消防、建筑等领域有着广阔的应用前景。Long afterglow material,generally refers to the material that after the removal of the excitation light source,the material can maintain a long time of luminescence.Ancient night pearl and some modern signs,fluorescent sticks and so on contain some long afterglow materials.The development of long afterglow materials has gone through the process of sulfide to aluminate.Among them,rare earth doped strontium aluminate material has long afterglow time,good brightness,stable chemical and thermal properties,friendly to the environment and non-toxic,and has gradually replaced sulfide long afterglow material,and has been widely used in the field of blue to green light luminescence long afterglow.At present,the long afterglow material has been widely used in the fields of signage,switch signage,luminous coating and other aspects,and has a broad application prospect in traffic,fire and construction.
