Abstract

An integrating sphere CCD-based measurement system has been developed to accurately characterize the opto-electronic performances of organic polymer light-emitting devices (OP-LEDs). Comparing this method with the previously developed lens-coupled method, we have found that the integrating sphere-based measurement method provides more stable and reliable optical data in comparison with the lens-coupled measurement method. In addition, we demonstrate that an inappropriate calibration of the OP-LED measurement system can greatly exaggerate the device performances.
