Abstract

The thermal lens technique has been used to measure absolute luminescent quantum yields of dyes in liquid and solid (PMMA) solutions. The validity of the approach has been established by measuring quantum yields of known compounds, and we stress the application to dye/polymer systems that would be suitable for luminescent solar concentrators. Our results for rhodamine 6G and Fluorol 555 give 0.93 ± 0.04 and 0.88 ± 0.03, respectively, for their quantum yield in PMMA.
