N2 Laser Induced Fluorescent Decay Spectra -A Laser Fluoresensor-

Abstract

The time behaviour of laser induced fluorescence for a variety of materials, such as crude oils, heavy oils and light oils is studied. The specificity of this "fluorescence decay spectrum" appears to be somewhat superior to that associated with the normal fluorescence spectrum. This laser fluoresensor may be of particular interest in the new form of environmental prove. experimental techniques and measurements are discussed in detail.
