Title: From luminescence solar concentrators to plastic scintillators: challenges and strategies to realize functional plastic waveguides
Abstract: The realization of high quality optical and electro-optical devices obtained through the insertion of optically-active nanomaterials inside polymeric matrices has allowed to combine the easy tunability of the optical properties and the robustness of the former with the possibility of obtaining light devices with an arbitrary shape of the latter. The application of this approach leaded to very promising results in luminescent solar concentrators (LSCs), a device consisting in slab doped or coated with chromophore capable of absorbing a fraction of incident light and re-emitting photons which are then focused on the device edges via total internal reflection. The integration of nanomaterials as chromophore in LSC enabled to realize large dimension devices which overcome the intrinsic limitations of previous generations and paved the way for new highly efficient technologies [1]. Recently, the know-how regarding photon-management and optical tunability [2] combined with surface engineering strategy of nanomaterials developed in LSCs technology, was also successfully applied in scintillating nanocomposites [3-4], yielding to the realization of scintillating composite materials with performances surpassing pure crystal- and plastic- based analogue technologies.
