A Ce:YAG-poly(methyl methacrylate) composite was prepared using in situ polymerization by embedding the Ce:YAG nanopowder in a blend of methyl methacrylate (MMA) and 2-methacrylic acid (MAA) monomers and activatingthe photopolymerization using a radical initiator. The obtained nanocomposite was yellow and transparent. Itscharacterization was performed using transmission electron microscopy, small angle X-ray scattering, 13C crosspolarizationmagic-angle spinning nuclear magnetic resonance, and photoluminescence spectroscopy. Results showedthat Ce:YAG nanoparticles are well dispersed in the polymeric matrix whose structure is organized in a lamellar shape.The luminescence properties of the nanocomposite do not show quenching or a significant spectral shift, indicating thatthe nanocomposite can be useful for advanced applications such as white LED construction.
