TL;DR: In this paper, an ion-beam modification of inner wall surfaces of tubes was examined by X-ray photoelectron spectroscopy, which showed the presence of amorphous carbon structures in the inner surfaces of Ne bombarded tubes.
Journal ArticleDOI
Phosphorescence quantum efficiency and intermolecular interaction of iridium(III) complexes in co-deposited films with organic semiconducting hosts
TL;DR: In this article, the absolute photoluminescence (PL) quantum efficiency (ηPL) of organic solid-state thin films by using an integrating sphere was accurately measured, showing that the ηPL of conventional organic materials used in organic light emitting diodes, such as a tris (8-quinolionolato)aluminum(III) complex (Alq3), and a phosphorescent 1.5mol%-fac-tris(2-phenylpyridyl)iridium(III):4, 4'-bis(carbaz
Journal ArticleDOI
White Electrophosphorescent Devices having Multi-organic Phosphors Doped Layers
TL;DR: In this article, a 3 nm-thick 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) layer was used to suppress the color change with an increase of a current density while keeping high efficiency.
