Room temperature luminescence properties of benzo(f)quinoline and phenanthrene adsorbed on. cap alpha. -cyclodextrin-sodium chloride mixtures
The room-temperature fluorescence (RTF) and room-temperature phosphorescence (RTP) intensities of benzo(f)quinoline (B(f)Q) and phenanthrene were obtained from several ..cap alpha..-cyclodextrin-sodium chloride mixtures. The results showed the importance of the initial wet chemistry in the sample preparation procedures for the observation of luminescence signal for compounds adsorbed on ..cap alpha..-cyclodextrin-sodium chloride mixtures. The data indicated that in order to obtain the optimum RTP and RTF signals, the solvent used to adsorb the analytes had to be saturated with ..cap alpha..-cyclodextrin. Also, the solid-surface fluorescence and phosphorescence quantum yield, triplet formation efficiency, and phosphorescence lifetime values were obtained for B(f)Q and phenanthrene adsorbed on 0.05% and 80% ..cap alpha..-cyclodextrin-sodium chloride mixtures. From these data, rate constants for phosphorescence and for radiationless transition from the triplet state were obtained.
