Abstract
Electron transfer between excited donor molecules followed by the back reaction is treated theoretically for a solid solution at high excita tion power. An expression for the average donor cation probability P+( t) is derived. Calculations of the time dependence for P+(t) are prese nted. The results indicate that the maximum value of P+(t) in the nonl inear quenching process is less than the corresponding values of P+(t) for the linear quenching at a low excitation power due to the depleti on of the accepters with time t. The restriction of the reaction volum e slows down the charge separation if the back charge transfer takes p lace.
