Abstract
A concentration dependence of the sensitized phosphorescence quantum yield of naphthalene (with benzophenone as a donor) in equimolar toluene solutions at 77 K is studied for concentrations of components ranging from 0.1 to 0.5 mole/litre. A nonmonotonic character of this dependence is established. With increasing solution concentration, intervals of increase (from 0.1 to 0.35) and decrease (from 0.35 to 0.5) of the sensitized phosphorescence quantum yield are observed. Reasons for this dependence are discussed.
