Patent ID: 7091271

Claim:
A nanocomposite optical plastic article, comprising: a plastic host material having a temperature sensitive optical vector x; a core shell nanoparticulate material dispersed into said plastic host material, said core shell nanoparticulate material having a core defined by a nanoparticulate material having a temperature sensitive optical vector x 1 , a shell defined by a coating material layer coated onto said core, said shell having a temperature sensitive optical vector x 2 and wherein said temperature sensitive optical vector x 1 is directionally opposed to said temperature sensitive optical vector x of said plastic host material, wherein said temperature sensitive optical vector x is defined as an index of refraction n plastic host , said temperature sensitive optical vector x 1 is defined as an index of refraction n core , and wherein said temperature sensitive optical vector x 2 is defined as an index of refraction of the shell n shell , wherein n shell <n plastic host <n core , wherein said core comprises a material selected from the group consisting of: ALON, aluminum oxide, beryllium oxide, cadmium sulfide, calcium carbonate, diamond, magnesium aluminate, magnesium fluoride, magnesium oxide, potassium titano phosphate, silica, tellurium oxide, yttrium oxide and zinc selenide.
