red-emitting phosphor
    Synthesis of a Red-emitting Phosphor with Low Cost and High Efficacy
    低成本高光效红色荧光粉的合成
    A New Red-Emitting Phosphor—Ca_4GdO(BO_3)_3:Eu~(3+)
    一种新型的红色荧光粉——Ca_4GdO(BO_3)_3:Eu~(3+)
    Luminescent Performance of Rare Earth SrZnO_2:Eu~(3+) Red-emitting Phosphor Powder
    稀土红色荧光粉SrZnO_2:Eu~(3+)的发光性能
    A new red-emitting phosphor,Ca_4GdO(BO_3)_3:Eu~(3+),was prepared by the solid-state reaction technique at high temperature and its luminescent properties were investigated.
    采用高温固相法制备了一种新型的红色荧光粉———Ca4GdO(BO3)3:Eu3+.
    The traditional preparation of (Y,Eu)2O3 was modified . Combining the compounding and the mixed methods, an usual method in lab has been developed . By precipitating Ba2+,Yand Eu3+ ions in stages ,and then calcinating the precipitate ,BaSO4mixed (Y,Eu)2O3 red-emitting phosphor was synthesized.
    本实验改进了传统的制备氧化钇铕荧光粉的方法,采用不同于"化合法"和"混合法"的实验室内常用的"干湿结合法",将Ba2+,Y3+,Eu3+用不同的溶液分步沉淀,然后再灼烧沉淀,制备出掺有BaSO4的红色荧光粉(Y,Eu)2O3.并对所得样品的发射光谱进行了测试.
    It has great potential for being explored as a new red-emitting phosphor because it can be easily excited by 254 nm,172 nm and X-ray light and emit bright red light. Its dominant emission peak is located at 610 nm and all other emission lines are very weak.
    它的主发射峰在610 nm,而且其它位置的发射峰都很弱; 它很容易被254nm、172 nm和X射线所激发而发出很强的红光,因此是一种具有潜在应用价值的红色荧光粉.
