摘要：
I present here the study of optical and fluorescence properties, structure and morphology of silica nanoparticles bearing laser dye molecules are electrostatically attached with high refractive index organic dopant in acrylic optical preform rod. The photo physical fluorescence behaviour of laser dye molecules at the surface of different size and shape of silica nanoparticles has been reported. The interaction of laser dye-nanoparticles, nature of particles, and effect of various sizes and shapes of silica nanoparticles on fluorescence properties has been investigated. The developed optical preform has high potential for possible applications as bio-analysis sensor probe. (C) 2012 Elsevier B.V. All rights reserved.
