Novel infrared-to-visible light upconversion devices are demonstrated by fabricating an organic light-emitting diode with an infrared-sensitizing layer. With a SnPc:C60 mixed layer as an infrared absorber and fac-tris(2-phenylpyridinato) iridium (III) (Irppy3) as an emitter, an infrared-to-green up-conversion device is demonstrated under 830-nm irradiation (see figure, ITO=indium tin oxide). The maximum photon-to-photon conversion efficiency is 2.7% at 15V. (Figure Presented) © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
