Abstract

Li2Gd4(MoO4)7: Eu3+/PMMA composite flakes (LGMP: Eu3+) have been obtained via embedding Eu3+ -activated LGM polycrystalline precursor powders into polymethyl methacrylate (PMMA). The precursor powder with a size of ∼7 μm is confirmed to form the sea-island-like structure by SEM, which is helpful to the stability of the particle-polymer coexistence network in LGMP: Eu3+ flakes. Differential photon-generating behaviors are revealed under short-wave radiation and the effectiveness of PMMA is verified in reducing the mutual collision probability and avoiding the powder agglomeration. Although the LGMP: Eu3+ system has lower powder content in contrast to the pure precursor, its luminosity is still comparable to the pure one due to its favorable particle dispersibility. Efficient photon-conversion and intense red-emission indicate the organic-inorganic composite of PMMA loaded LGM: Eu3+ system is a potential candidate for solid-state lighting and color displays.
