摘要： This disclosure features a blend, or use together in at least two layers of an article of manufacture, of a first persistent phosphor, a second persistent phosphor and a third phosphor. The first persistent phosphor has a formula I: Cax-y-z-aAaAl2-m-n-o-pOd:Euy,REz,Bm,Znn,Coo,Scp I where the variables are defined in the disclosure. The second persistent phosphor has a formula II: Srx-y-z-aAaAl14-m-n-o-pOd:Euy,REz,Bm,Znn,Coo,Scp II where the variables are defined in the disclosure. The third phosphor is a non-persistent phosphor that is excited at a wavelength in a range of 300-500 nm. Also featured is an article of manufacture including the blend or the phosphors present in at least two layers. Once the blend or layered structure comprising the three phosphors has been excited it can appear white in an absence of ambient light.
摘要翻译：本公开的特征在于共混物，或者在制品的至少两层中一起使用第一持久荧光体，第二持续荧光体和第三荧光体。第一持久性荧光体具有式I：Cax-y-z-aAaAl2-m-n-o-pOd：Euy，REz，Bm，Znn，Coo，Scp I，其中变量在本公开中定义。第二持续荧光体具有式II：Srx-y-z-aAaAl14-m-n-o-pOd：Euy，REz，Bm，Znn，Coo，Scp II，其中变量在本公开中定义。第三荧光体是在300-500nm范围内的波长下激发的非持久荧光体。还有一个包括共混物或至少两层中存在的荧光体的制品。一旦包含三种荧光体的共混物或分层结构已经被激发，它可以在不存在环境光的情况下显现为白色。
