Abstract

An optical cell system was developed for online research into the luminescence spectrum under conditions of extremely high hydrostatic pressure up to 60 MPa. The optical cell, which had three 8 mm thick sapphire windows 16 mm in diameter, was mounted directly onto a fluorescence spectrometer. Hydrostatic pressure was achieved through a hand pump and monitored through a pressure sensor. The optical cell system could be used separately. And more importantly, the system could be connected to a high-pressure flowing system for online flowing luminescence measurement. For system validation, fluorescence spectra of Rose Bengal solution using the high-pressure cell were compared with the standard sample holder. Using the system, fluorescence spectra of Rose Bengal dissolved in distilled water were measured under different pressures at room temperature. The fluorescence intensity of Rose Bengal solution changed with pressures, but the peak positions were almost the same.
