Abstract:
Observations of the transient behaviour of electroluminescence in sublimation flakes have shown that quenching of the delayed electro-luminescence component by the carriers themselves becomes important at high currents. The results show quenching is of the same order as observed for carrier quenching of optically produced triplet excitons. No quenching was observed in thick crystals though carrier densities of the same order are present. This is presumably due to the difference in recombination zone width which may be larger in these thick crystals.
