Abstract

A Ce:YAG-poly(methyl methacrylate) (PMMA) composite was prepared by using the melt compounding method. The Structure and morphology were investigated by X-ray diffractometry, transmission electron microscopy, and small-angle X-ray scattering. The optical properties (emission, excitation, and fluorescence decay rate) of the composite were studied by using photoluminescence spectroscopy. The polymer−filler interactions were studied using 13C cross-polarization magic-angle spinning NMR spectroscopy (13C{1H} CP-MAS NMR). The results indicated that Ce:YAG particlesare well-dispersed in the PMMA matrix without loss of their luminescence properties or significant spectral shift, thus suggesting that this composite can be valuable for advancedapplications in white LED manufacture. A demonstration of its efficiency in white LED devices is also reported.
