Abstract
The liminescent decay of the red "exciton" emission of GaP(Zn, O) has been analyzed for the case of high-density excitation in the temperature range (40-100) °K. The decay behavior under these conditions has previously been poorly understood. We show that kinetics based on a quasi-thermal-equilibrium model adequately explain the literature data. The crucial step in the analysis resides in the use of proper impurity activation energies. Advantages of the present method of analysis, based on its relative simplicity, are also discussed.
