A New Fiber-Optic-Based Phase-Resolved Phosphorescence Spectrometer.

Abstract

A new phase-resolved phosphorescence spectrometer is described which employs a cw ultraviolet argon-ion laser excitation source. THe excitation and phosphorescence radiation is carries to and from the sample through inexpensive optical fibers. Typical detection limits are less than 85 nM for all of the lumiphores studied. The new instrument is shown to be applicable to the simultaneous determination of the individual components in binary and ternary mixtures. In addition, the new instrument is used for the generation of multidimensional data sets. Specifically, the phase-resolved phosphorescence intensity vs. detector phase angle setting are collected rapidly (10 minutes) for several of the lumiphores studied. These multidimensional data arrays are subsequently used for multicomponent analyses. Keywords: Fiber optics; Sensors; Time resolved luminescence; Phosphorimetry.
