摘要： A blue persistent phosphor composition is provided, along with methods for making and using the composition. More specifically, in one embodiment, the phosphor includes a material having a formula of A3M10-xC1+x(O20-xNx):Eu, RE wherein A may be Ba, Sr, Ca, K, Na or a combination thereof, M may be Al, B, Zn, Co, Ga, Sc or a combination thereof, and C may be Si or Ge or a combination thereof; x is between 0.001 and 5.0; and RE is Dy, Nd, Er, Ho, Tm, Yb, Sm or a combination thereof. Beneficial embodiments use Sr, Si and a combination of Al and B to produce phosphors that are blue in color and have a slower rate of decay. In another embodiment, methods are provided for making persistent phosphors having the formulations above. Other embodiments provide applications for such a phosphor, including uses in toys, emergency equipment, clothing, and instrument panels, among others.
摘要翻译：提供蓝色持久荧光粉组合物，以及制备和使用组合物的方法。更具体地，在一个实施方案中，荧光体包括具有式A3M10-xC1 + x（O20-xNx）：Eu，RE的材料，其中A可以是Ba，Sr，Ca，K，Na或其组合，M可以 Al，B，Zn，Co，Ga，Sc或它们的组合，C可以是Si或Ge或它们的组合; x在0.001和5.0之间; RE是Dy，Nd，Er，Ho，Tm，Yb，Sm或它们的组合。有利的实施例使用Sr，Si和Al和B的组合来产生蓝色并具有较慢的衰变速率的荧光体。在另一个实施方案中，提供了制备具有上述配方的持久性荧光体的方法。其他实施例提供了这样的荧光体的应用，包括在玩具，应急设备，衣服和仪表板等中的用途。
