Highly efficient top-emitting white organic electroluminescent devices

Abstract: We have developed highly efficient white top-emitting organic light-emitting devices (TOLEDs) with broad emission by modifying both anode and cathode. To alleviate the undesirable microcavity effect and obtain "broad" white emission, CF xcoated Ag anode with modified reflectivity and an index-matching layer (SnO 2 ) capped on thin Ca/Ag cathode with a maximal transparency of 80% were employed. A top-emitting broad white light device based on the dual layer architecture of light blue and yellow emitters with on… Show more

“…1,2 The most widely studied materials employed for optoelectronic devices that accomplish these properties are several binary oxides like: In 2 O 3 , Ga 2 O 3 , Al 2 O 3 , ZnO, SnO 2 and TiO 2 . [3][4][5] The widespread use of In 2 O 3 in industrial processes covers the fabrication of window layers in solar cells, [6][7][8] light-emitting diodes, 9,10 electrochromic windows, 11 liquid-crystal displays, 12,13 and gas sensors. 14,15 Due to the scarcity and high cost to obtain indium metal, new 3 systems, like Sn-doped In 2 O 3 (ITO) and corundum-type In 2-2x Zn x Sn x O 3 (x ≤ 0.4, or ZITO), have been developed to cut the prize of the production system.…”

“…The CIE coordinates of bottom-and top-emission are also denoted for reference. The stronger microcavity effect for the topemitting OLED will produce narrower FWMH, better color purity and better efficiency [16]. 2 , the luminous efficiency of top-and bottom-emitting OLED are 18.5 and 16.8 cd/A, respectively.…”
