Influence of Blending Temperature on Fluorescence Properties of Silicone Rubber Matrix Eu(TTA)2(phen)(MA) Composites

Keywords： rare earth complex

A series of fluorescent composites were prepared by blending silicone rubber with Eu(TTA)2(phen)(MA). The influence of mechanical blending temperature on fluorescent intensity of composites and dispersion of rare earth complexes in the SiR matrix were investigated. As for the cured rubber, it is found that its fluorescent intensity is relatively low compared with that of uncured rubber. Low temperature is beneficial to dispersion of Eu(TTA)2(phen)(MA) homogeneously. When the amount of rare earth complexes is low, the fluorescent intensity of composites prepared by mechanical blending method above melting point of Eu(TTA)2(phen)(MA) is much higher than that of composites prepared below melting point.
