Fabrication and Characterization of Blue Organic Light-emitting Diodes
Abstract
Organic light-emitting diode (OLED) technology has demonstrated high efficiency and brightness, leading to a strong commercial interest. One remaining problem with the OLED technology is the efficiency and color saturation for blue light emitters. A series of experiments were developed to test the brightness and light disposition of organic films. The different combinations of N,N'-Bis- (1-naphthalenyl)-N,N'-bis-phenyl-(1,1'-biphenyl)-4,4'-diamine) (NPB), 1, 3, 5-Tri(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl) (TPBI), and doping cesium carbonate (Cs2CO3) were investigated to determine which recipe results in brighter luminance and greater longevity.
