TLDR
In this article, the authors used light-emitting diodes, properly calibrated, provide a convenient method for measuring absolute intensity, which is the ratio between fluorescence intensity and that of a reference standard, typically a masked uranyl glass.About:

Chapter 9 Maturation of Organic Matter as Revealed by Microscopic Methods: Applications and Limitations of Vitrinite Reflectance, and Continuous Spectral and Pulsed Laser Fluorescence Spectroscopy
TL;DR: In this article, the complexity, usefulness and limitations of vitrinite reflectance, spectral fluorescence, and laser fluorescence utilize incident-light microscopy for the evaluation of maturation of crude oils and condensates.
Journal ArticleDOI
Application of confocal laser-scanning microscopy (CLSM) to autofluorescent organic and mineral matter in peat, coals and siliciclastic sedimentary rocks — A qualitative approach
TL;DR: In this paper, a non-invasive and non-destructive laser-raster technique is applied to characterize in situ autofluorescent organic particles at micron to sub-micron scale resolution in polished whole rock pellets.
Journal ArticleDOI
Application of spectral fluorescence microscopy for the characterization of Athabasca bitumen vacuum bottoms
TL;DR: In this article, the relationship between visible light region fluorescence properties and gross chemical composition of ten narrow cut subfractions of Athabasca bitumen separated by super critical fluid extraction has been studied.
Journal ArticleDOI
A new calibration procedure for fluorescence measurements of sedimentary organic matter
TL;DR: In this article, a new microspectrofluorimetry calibration method has been developed by three laboratories, which allows quantification, in terms of spectral radiance, of the fluorescence emitted by oils and kerogens.
Journal ArticleDOI
Four-dimensional fluorescence imaging of oil generation: development of a new fluorescence imaging technique
TL;DR: In this article, a new fluorescence imaging technique was developed for visualization of the complex array of fluorescence spectral data and of progressive petroleum generation, where particle-specific chemical variabilities are captured by fluorescence spectrum data, which are represented as surfaces, containing information regarding relative intensities, wavelengths, and principal component (PC1) projections of the raw spectral data.
