ABSTRACT

The objective of this postdoctoral position concerns the synthesis and the characterization of novel radioluminescent nanocomposite polymers for the development of ionizing-radiation detectors more efficient than existing devices. To achieve this goal, we propose to incorporate sub-micron 2D resonant structures in conventional radioluminescent polymers (based on polystyrene and derivatives), in order to both improve the collection of scintillation photons and amplify their generation (effect Purcell). Nevertheless, this approach requires polymers with a higher optical index than standard materials. An effective way to increase the overall index of the material would be to introduce nano-objects with higher optical index into the polymer matrix. Diamond is the non-metallic material with the highest refractive index (2.42). It is also transparent in the visible and its surface chemistry easily lends itself to many functionalization routes. These criteria, together with their compatibility with the nanostructuration processes that will be implemented, make it a prime candidate for the doping of scintillating polymers.
