Paper Abstract

In this paper we propose the study of nanocomposites for white light emission in a semiconductor device, by incorporating the yttrium aluminum garnet doped with cerium ions (YAG:Ce3+), into a polymeric matrix of poly methyl methacrylate. The co-precipitation method was used for the synthesis of YAG:Ce yellow phosphor. The transition from the amorphous state to the crystalline was observed at a temperature of 1200°C. In order to obtain a better dispersion of the nanoparticles in the polymeric matrix has been chosen a capping agent. The structural analysis of the nanocomposite and the phosphor were studied by Fourier transform infrared spectroscopy and x-ray diffraction, morphological properties were investigated by scanning electron microscope, and photoluminescence spectrometry has highlighted the applicability of phosphors and, implicitly, of the nanocomposite for application in emitting optoelectronics.
