Investigation on the escaped and trapped emission in organic light-emitting devices

The escaped and trapped emission of small molecule based bottom emission organic light-emitting diodes was investigated by using an integrating sphere and a fiber spectrometer and a glass hemisphere. It was found that the maximum external coupling ratio rext, namely the ratio of escaped emission to...
