摘要： A photoluminescent device and a photoluminescent exit sign. The photoluminescent device includes a polymer matrix having a light-emitting exterior surface for emission of photoluminescent light therefrom. The photoluminescent device has a plurality of UV or visible-light excited phosphor particles included in the polymer matrix. The phosphor particles have a concentration greater in an exterior region of the polymer matrix proximate the light-emitting exterior surface than in an interior region of the polymer matrix. The exit sign includes at least two plates interlocked together with at least one typographical character disposed on the plates. The typographical character is formed from the polymer matrix containing the phosphor particles.
