    Abstract: In one embodiment, a light emitting device comprises: a lighting element located in a housing, wherein the housing is formed from a polymer composition comprising: a polymer material; and a coated conversion material. The coated conversion material is selected from a coated conversion material, coated yttrium aluminum garnet (YAG) doped with rare earth elements, coated terbium aluminum garnet doped with rare earth elements, coated silicate (BOSE) doped with rare earth elements; coated nitrido silicates doped with rare earth elements; coated nitride orthosilicate doped with rare earth elements, coated oxonitridoaluminosilicates doped with rare earth elements; as well as combinations comprising at least one of the foregoing. After the coated conversion material has been exposed to an excitation source, the coated conversion material has a luminescence lifetime of less than 10−4 seconds when the excitation source is removed.
