VACUUM IJLTRAVIOLE1I ' EXCITED LUMINCENCE OF ORGANIC SYSTE. A REVIEW

The fluorescent behavior of liquid organic solutions and of pure solvents under excitation in the vacuum ultraviolet is presented. Wavelength dependence, dilution effects and quenching effects are considered. Basic differences between aromatic and non-aromatic solvents are found. A computation of the theoretical energy yield of a common scintillator solution based on the virtual photon description of fast par tides is cited. Some basic features of the vacuum ultravio-. let excited fluorescence of solids demonstrate the strong in-fluence of the structure of the environment. Possible impli-cations of photoconductivity measurements are forwarded
