Abstract
In this paper, we report on theProd. Type: FTP fabrication and characterization of blue and white light emitting devices based on two fluorene-carbazole containing dendrimers and para-sexiphenyl (6P) oligomers. Blue light emitting diodes were fabricated using 9â²,9â³-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis-9â²H-9,3â²:6â²,9â³-tercarbazole (OFC-G2) and 9â²,9â³-(9,9â²-spirobi[fluorene]-2,7-diyl)bis-9â²H-9,3â²:6â²,9â³-tercarbazole (SBFC-G2) dendrimers as a hole transport and emissive layer (EML) and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) as an electron transport layer. White light emitting diodes were fabricated using 6P and these two dendrimers as an EML. OLED device with the structure of ITO/PEDOT:PSS (50Â nm)/OFC-G2 (40Â nm)/6P (20Â nm)/LiF:Al (0.5:100Â nm) shows maximum luminance of nearly 1400Â cd/m2 and a Commission Internationale de l'Eclairage chromaticity coordinates of (0.27, 0.30) at 12Â V.
