Abstract:
1. A flexible microcavity structure made of organic materials using spin-coating technique allowing large area structures using a roll-to-roll process, comprising: a) at least one first polymer layer; b) at least one second polymer layer; and c) a cavity layer of polyvinyl carbazole; wherein said cavity layer has quantum dots embedded therein for realizing an electrically pumped microcavity emitter, said quantum dots including InGaP and having an emission with a wavelength of 670 nm, and said cavity layer having a thickness equal to an integer multiple of half said wavelength of said emission of said quantum dots; wherein each of said at least one first polymer layer alternates with said at least one second polymer layer to form a pair of distributed Bragg reflecting mirrors; and wherein said cavity layer is sandwiched between said pair of distributed Bragg reflecting mirrors.
