Visible analysis of fluorescence characteristics of crude oil based on chromaticity inversion

Based on the principle of chromaticity, compile fluorescence spectrums´ chromaticity inversion program, and calculate the color coordinates of crude oil excited by monochromatic purple light from external light source. Color coordinates can reflect different aromatic compounds in different components of crude oil, because fluorescence spectrums are different. In this way, the experimental results become visible, and facilitate the color distinct between fluorescence of different crude oil. From the color coordinate, we can further study the maturity of crude oil.
