Advanced Ceramics Report, November, 2002

Scientists from Brown University, USA, say that they have made nanocomposite arrays by filling nanopores in anodized alumina with an organic dye. The composites exhibited a much higher fluorescence yield than conventional films of the dye, the researchers report.

According to lead researcher Dr Igor Levitsky "This unique property of the organic-dye nanocomposite opens up new possibilities in organic molecular photonics in the condensed phase. It is known that fluorescence of organic molecules in the solid state is affected by self-quenching processes caused by molecular aggregation. In our case, the aggregation is strongly suppressed, so we can observe the high fluorescence yield."

Levitsky and his colleagues created the nanocomposite arrays by...
