White organic light-emitting diodes based on tandem structures
White organic light-emitting diodes made of two electroluminescent (EL) units connected by a charge generation layer were fabricated. Thus, with a tandem structure of indium tin oxide/ N , N ′ -di(naphthalene-1-yl)- N , N ′ -diphenyl-benzidine (NPB)/9,10-bis-( β -naphthyl)- anthrene (ADN)/2,9-dimeth...
