Microcavity light emitting diodes based on materials with broad emission spectrum, such as tris (8-hydroxyquinoline) aluminum (Alq 3 ), typically exhibit a significant blue shift of the emission wavelength with increasing viewing angle. In this work, we investigate the influence of the organic layer thickness on the angular dependence of the emission spectrum in low Q-factor microcavity OLEDs...
In this work, we present a systematic study of the emission from bilayer organic microcavity light emitting diodes with two metal mirrors. The devices consisting of two organic layers, N,N′-di(naphthalene-1-yl)-N,N′-diphenylbenzidine as the hole transport layer and tris (8-hydroxyquinoline) aluminum as the emitting layer, and two metal mirrors were fabricated and characterized by transmittance, reflectance,...
Microcavity organic light emitting diodes (OLEDs) have attracted great attention because they can reduce the width of emission spectra from organic materials enhance brightness and achieve multipeak emission from the same material. In this work, we have fabricated microcavity OLEDs with widely used organic materials, such as N,N'-di(naphthalene-1-yl)-N,N'-diphenylbenzidine (NPB) as a hole transport...
