摘要
The role of F_(4) 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 Förster energy transfer between F_(4)TCNQ and Alq3 is close to 0 nm and Dexter energy transfer dominates in the quenching process.
