Abstract
A flexible microcavity structure made of organic materials using spin-coating technique for allowing large area structures using a roll-to-roll process. The structure includes at least one first polymer layer, at least one second polymer layer, and a cavity layer. The cavity layer has quantum dots embedded therein for realizing an electrically pumped microcavity emitter. The at least one first polymer layer alternates with the at least one second polymer layer, respectively, to form a pair of distributed Bragg reflecting mirrors. The cavity layer is sandwiched between the pair of distributed Bragg reflecting mirrors.
