经过近两年的努力,包头稀土研究院研制出一种新型稀土钛酸钙体系红色长余辉荧光粉,其初始亮度达到国内商用红粉的200%以上,具有发光品质优良、余辉性能良好和物理化学性能稳定,合成工艺简单等特点,是目前行业中难得的一种新型红色长余辉发光材料。稀土长余辉发光材料是一类光致蓄能功能材料,其原理是在吸收太阳光或者其他光的能量后,将部分能量存储起来,然后再缓慢地把存储的能量以可见光的形式释放出来。这种新型节能材料广泛应用于弱光照明、应急指示、建筑装饰和工艺美术等领域,近年来又逐渐拓展到信息存储、高能射线探测、成像显示等应用领域,日益引起了人们的重视。从三原色原理考虑,将颜色为红、绿、蓝三种颜色的长余辉发光材料按一定比例混合,可得到任何一种颜色的 After nearly two years of efforts, Baotou Rare Earth Research Institute has developed a new rare earth calcium titanate red long afterglow phosphor, the initial brightness of more than 200% of domestic commercial pink, with good luminous quality, afterglow performance is good and physical and chemical Stable performance, simple synthetic process and so on. It is a rare new red long afterglow luminescent material in the current industry. Rare-earth long afterglow luminescent materials are a type of photo-induced energy storage functional materials. The principle is that after absorbing the energy of sunlight or other light, part of the energy is stored, and then the stored energy is slowly released in the form of visible light. The new energy-saving materials are widely used in the fields of low light illumination, emergency instructions, architectural decoration and arts and crafts. In recent years, the new energy-saving materials have been gradually extended to such fields as information storage, high-energy radiation detection and imaging display, attracting more and more attention. From the principle of the three primary colors, the color is red, green and blue long afterglow luminescent materials are mixed according to a certain percentage, can be any color
