Abstract

en

The emission spectra of pure and doped poly(methyl methacrylate) films are recorded and discussed with respect of using the films as luminescence solar concentrators. The doping materials are polyaromatic hydrocarbons and some dyes. Most of the emitted bands appear in the region 700 to 400 nm when the doped PMMA films are excited with UV radiation.

Die Emissionsspektren von reinen und dotierten Poly(methylmethacrylat)-Filmen wurden registriert und im Hinblick auf die Verwendung der Filme als Lumineszenz-Solarenergie-Konzentratoren diskutiert. Als Dotierungssubstanzen wurden polyaromatische Kohlenwasserstoffe und einige Farbstoffe eingesetzt. Die meisten emittierten Banden erscheinen im Bereich 700 bis 400 nm, wenn die dotierten PMMA-Filme mit UV-Licht angeregt werden.
