Abstract
A nanocomposite optical plastic article has a plastic host material with a temperature sensitive optical vector (x) and a core shell nanoparticulate material dispersed into the plastic host material. The core shell nanoparticulate material is characterized by a core defined by a nanoparticulate material which has a temperature sensitive optical vector (x1) and a shell defined by a coating material layer coated onto the core. It is important to the invention that temperature sensitive vector (x1) is directionally opposed to the temperature sensitive optical vector (x) and nshell<nplastic host<ncore.
