Fluorescence Decay Times Of Multicomponent Microscopic Materials By Pulsed Laser Excitation

A fast analog technique developed for the determination of fluorescence emission parameters of microscopic geological particles is applied to a variety of samples. Presented here are fluorescence data from liptinite coal macerals, analysis of fluorescence emitted from crude oils, applications to fiber analysis and plastic scintillators. Characteristic decay times in the nanosecond and subnanosecond range are given along with time-resolved emission spectra.
