Abstract

Ce:YAG-poly(methyl methacrylate) (PMMA) composites were prepared by using a melt compoundingmethod, adding several amounts of Ce:YAG in the range 0.1-5wt.%. The optical properties of the obtained composites and of the composites combined with a blue LED were measured to investigate the effect of the amount of Ce:YAG on the resulting emitted light in view of possible application in white LED manufacture. An increase in Ce:YAG amount caused an increase in the emission and a shift of 15 nm, influencing the white LED performance. The structure andmorphology of the composites were studied. The results show that the interaction between the two components, observed by using solid state NMR experiments, are the responsible for the observed shift.
