First Claim
Patent Images
1. An object comprising:
- a low rare earth mineral photoluminescent structure incorporated onto or into one or more portions of said object, said object being a photoluminescent object, said low rare earth mineral photoluminescent structure comprising;
a phosphorescent layer that substantially converts at least a portion of incident electromagnetic radiation to a primary emission, said phosphorescent layer comprising one or more phosphorescent materials having substantially low rare earth mineral content of less than about 2.0 weight percent with an absorption spectrum that at least partially overlaps with incident electromagnetic radiation, andone or more fluorescent layers that wholly or partially convert at least said primary emission to a secondary emission, said one or more fluorescent layers having an absorption spectrum that overlaps with at least a portion of said primary emission.
