The temperature dependency of the phosphorescence properties of aromatic hydrocarbons (phenanthrene) in alcoholic glasses exhibits a number of phenomena that have not been previously described. Chief among these are the effects of added gases (O/sub 2/, N/sub 2/, C/sub 2/H/sub 6/, Ar, etc.), some of which produce major changes in the luminescence characteristics. These are discussed, and rationalized in terms of a model which presumes that O/sub 2/ and N/sub 2/ disrupt the normal hydrogen bonding process between alcohol molecules.
