Abstract

Fluorescence quenching of benzopurpurin (BP) by HC1 in methanol is investigated. The observed extremely efficient quenching is attributed to the formation of a non-fluorescent exciplex between BP and HC1. Other pollutant gases, such as H2S and NH3, were found not to effect the fluorescence of BP. Possibilities of using this finding to develop a fibre optic HG sensor are discussed.
