Abstract
The aim of Chapter 7 is to investigate the prospects of realizing an electrically pumped laser using OLEDs with field-effect electron transport. First, the potential of the structure as laser device configuration is analyzed. The advantages as well as the existing limitations are highlighted. Next, amplified spontaneous emission measurements and optically pumped lasing experiments are performed. Stimulated emission in the host-guest system Alq3:DCM2 and in organic layer stacks including hole- and electron-transporting layers used in OLEDs with field-effect assisted electron transport are studied. In the end, the different possibilities to incorporate an optical feedback mechanism in the device are discussed.
