Abstract

We report on experiments conducted to investigate dissolved sugar luminescence in order to clarify the photophysics of the process. The conclusions we have drawn provide evidence of a quadratic increase in the luminescence response at small concentrations (<100 g/l) and a linear increase at relatively large concentrations (>200 g/l). We consider the possible effect of excimer formation and luminescence. The apparently existing intermolecular interaction existence is also supported by observed variations in the absorption spectra. A temporal response to a short light pulse was measured, revealing a time delay of about 15 ns.
