Abstract:
1. A luminescent or scintillation material, comprising: a nanoparticle with a core having an index of refraction and at least one shell partially or totally enclosing the core, wherein when an additional shell is present, each partially or totally enclose the adjacent shell closest to the core, wherein each of the at least one shells has an index of refraction, wherein the shell enclosing the core has an index of refraction that is about 0.0001 to 50% different than the index of refraction of the core, wherein when one or more additional shells are present each will have an index of refraction that is about 0.0001 to 20% different than the adjacent shell closest to the core, wherein the outer most shell furthest away from the core has an index of refraction that is about 0.0001 to 10% different from that of the index of refraction of a matrix material in which the nanoparticle is dispersed, wherein the core is a non-metal, and wherein each shell is independently selected from a non-metal.
