A method for the determination of the room-temperature fluorescence and room-temperature phosphorescence quantum yields for organic compounds adsorbed on different surfaces is described and evaluated. Quantum yield values were determined for compounds adsorbed on sodium acetate, a polyacrylic acid-NaBr mixture, and filter paper. The approach employs conventional instrumentation with various instrumental modifications for obtaining accurate and reproducible data. Quantum yield values at room temperature with and without nitrogen flowing over the solid surfaces are compared. The results show that the method is very reproducible and relatively low quantum yield values can be obtained. 17 references, 1 figure, 3 tables.
