Realization of blue, green, and white inverted microcavity top-emitting organic light-emitting devices based on the same emitting layer.
High efficiency blue, green, and white inverted microcavity top-emitting organic light-emitting devices based on blue emitter p-bis(p-N,N-diphenyl-amino-styryl) benzene-doped 2-methyl-9,10-di(2-naphthyl) anthracene as the emitting layer are demonstrated. The different colors can be well realized by simply changing the thickness of the hole-transporting layer, thus modifying the cavity length to obtain various resonance wavelengths. The comprehensive analysis on the emission mechanism is presented.
