中文摘要	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.
