摘要: White organic light-emitting device (WOLED) with Sm:Ag black cathode was first reported. The effect of the on performances (such as efficiency, luminance, contrast ratio at different angle and EL spectra, etc) WOLEDs discussed. We found that efficiency WOLED comparable to conventional Mg:Ag cathode. For example, is just 15% lower than MgAg However, (CR) 105:1 under 140 lx ambient lighting a high brightness 1000 cd/m2, which four times better Besides, CR insensitive viewing less 50°.
