In the last two decades, intense research on luminescent materials have been actively pursued due to their numerous applications in display and light emitting devices.

Abstract
In the last two decades, intense research on luminescent materials have been actively pursued due to their numerous applications in display and light emitting devices. One way to design light-emitting materials consists in incorporatingluminescent fillers within a “non-optically active” polymeric matrix leading to composite materials. Several works have been reported in the literature related to emissive polymeric composite materials based on organic dyes, nanoparticles, such as semiconductor quantum dots and rare-earth doped oxides and also on coordination complexes of lanthanide or iridium ions. Following this trend-line, this Thesis aims to the preparation of Photoluminescent polymeric nanocomposite incorporating in different polymeric matrices different Photoluminescent inorganic particles. The technique utilized for the preparation of the polymeric nanocomposites was UVcuring. In this Thesis it was investigated both acrylic and epoxy systems, demonstrating that UVcuring is a suitable technique to produce Photoluminescent materials both via radical and via cationic photopolymerization process. Moreover experiments were conducted in order to better understand the interaction between the polymeric matrix and the optical properties of the inorganic fillers. Finally different trials were performed in order to achieve a way to tailor the emission properties on specific target related to different application. This led to the synthesis of multifunctional materials in which more than one property (both optical and mechanical) was achieved in one coating.File | Dimensione | Formato | |
