Solid-state dye materials — •Jennifer Krause, Andrea Schuy, Robert Lepski, and Dominik Schaniel — I. Physikalisches Institut, Universität zu Köln, Köln, Germany

Solid-state dye materials are highly requested for applications in tunable lasers or as luminescent materials. We synthesized solid-state dye materials by embedment of organic dyes into anorganic silica matrices and characterized them by absorbance and luminescence spectroscopy. The influence of the matrix parameters like pore size and pH-value as well as the concentration dependence on the luminescence properties has been determined. Furthermore the photostability was compared to that of liquid dyes and embedded in other matrix materials.
