Improving the Performance of Phosphorescent Based White Polymer Light Emitting Devices Using Iridium Complexes
Polymer White-light-emitting devices WPLEDs with single layer structures are fabricated by the spincoating method. The device structure used here is indium-tin-oxide(ITO)/polyethylene dioxythiophene(PEDOT:PSS)/polymer blend/Ca/Al, whose blend consists poly N-vinylcarbazole(PVK) hole transporting host polymer, an electron transporting materials 2-4-biphenylyl-5-tert-butylphenyl1,3,4-oxadiazole(P...
متن کاملDegradation mechanism of phosphorescent-dye-doped polymer light-emitting diodes
The degradation mechanism of phosphorescent-dye-doped polymer light-emitting diodes ~PLEDs! is investigated. The active medium of our PLED is a polymer blend comprising poly~vinylcarbazole! ~PVK!, @2-~4-biphenylyl!-5-~4-tert-butyl-phenyl!-1,3,4-oxadiazole# ~t-PBD!, and platinum~II!-2,8,12,17-tetraethyl-3,7,13,18-tetramethylporphyrin ~PtOX!. The cyclic voltammetry result shows that the reductive...
متن کاملPhosphorescent Molecularly Doped Light-Emitting Diodes with Blended Polymer Host and Wide Emission Spectra
Stable green light emission and high efficiency organic devices with three polymer layers were fabricated using bis[2-(4'-tert-butylphenyl)-1-phenyl-1H-benzoimidazole-N,C²'] iridium(III) (acetylacetonate) doped in blended host materials. The 1 wt% doping concentration showed maximum luminance of 7841 cd/cm² at 25.6 V and maximum current efficiency of 9.95 cd/A at 17.2 V. The electroluminescence...
متن کاملPhosphorescent Organic Light-Emitting Devices: Working Principle and Iridium Based Emitter Materials
Even though organic light-emitting device (OLED) technology has evolved to a point where it is now an important competitor to liquid crystal displays (LCDs), further scientific efforts devoted to the design, engineering and fabrication of OLEDs are required for complete commercialization of this technology. Along these lines, the present work reviews the essentials of OLED technology putting sp...
متن کاملEnergy transfer and device performance in phosphorescent dye doped polymer light emitting diodes
Singlet and triplet–triplet energy transfer in phosphorescent dye doped polymer light emitting devices were investigated. Poly(N-vinylcarbazol) and poly@9,98-di-n-hexyl-2,7-fluorene-alt1,4-(2,5-di-n-hexyloxy)phenylene] ~PFHP! were selected as the host polymer for the phosphorescent dopants fac-tris~2-phenylpyridine! iridium~III! @Ir(ppy)3# and 2,3,7,8,12,13, 17,18-octaethyl-21H,23H-porphyrin pl...
