Abstract

New fiber-optic instrumentation for phosphorescence-lifetime determinations and for steady-state phosphorescence measurements is shown to perform comparably to conventional instrumentation. The importance of optimal glass formation in the fiber-optic sample cell is considered in some detail. Detection limits for acetophenone, benzophenone, and <i>p</i>-nitrophenol are reported, and phosphorescence lifetimes are measured for several compounds, with values ranging from 2.5 ms to 4.7 s.
