Abstract:Two types of organic light-emitting diodes with structures of ITO/N,N′-bis(1-naphthyl)-N,N ′-diphenyl,1,1′-biphenyl-4,4′-diamine (NPB)/tris(8-hydroquinolinato)aluminum(Alq 3 )/2,9-dimethyl-4,7-diphenyl-l,10-phenanthroline(BCP)/Alq 3 :4-dicyanomethylene-2-(tert-butyl)-6-methyl-4H-pyran(DCJTB)/Alq 3 /Al and ITO/NPB/BCP/Alq 3 /Alq 3 :DCJTB/Alq 3 /Al were studied. NPB was chosen as a hole-transporting/blue-emitting layer. Alq 3 adjacent to BCP acted as a green emitting layer while that adjacent to the Al cathode ac… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
