英文摘要	The effect of the concentration of 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl- 9-enyl)-4H-pyran(DCJTB) as dopant in tris(8-hydroxyquinoline) aluminium (Alq(3)) on the charge carrier recombination was studied by transient electroluminescence (EL). The electron-hole recombination coefficient (gamma) was determined from the long-time component of the temporal decay of the EL intensity after a rectangular voltage pulse was turned off. It was found that the coefficient monotonically decreased with an increase in the DCJTB-doping concentration. The monotonic decrease is attributed to concentration quenching on the excitons and coincided well with the reduction of the EL efficiency.
