ABSTRACT:
The current invention provides a persistent phosphor blend, along with techniques for making and using the blend. The persistent phosphor blend is made of at least one persistent phosphor combined with at least one other phosphor, where the excitation spectra of the one or more other phosphors overlap the emission spectra of the one or more persistent phosphors. The choice of the phosphors used allows the decay time and emission colors to be tuned for the specific application. In another embodiment, the invention provides a method for making persistent phosphor blends with tunable colors. In yet another embodiment, applications for such a persistent phosphor blend are provided.
