Abstract ：The role of F4 TCNQ as an exciton quenching material in thin organic light-emitting films is investigated by means of in situ photoluminescence measurements. C60 was used as another quenching material in the experiment for comparison, with Alq3 as a common organic light-emitting material. The effect of the growth sequence of the materials on quenching was also examined. It is found that the radius of F?rster energy transfer between F4 TCNQ and Alq3 is close to 0 nm and Dexter energy transfer dominates in the quenching process.
