Özet
In this paper, we report on the Prod. 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 9',9 ''-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis-9' H-9,3':6',9 ''-tercarbazole (OFC-G2) and 9',9 ''-(9,9'-spirobi[fluorene]-2,7-diyl)bis-9'H-9,3':6',9 ''-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 (50 nm)/OFC-G2 (40 nm)/6P (20 nm)/LiF:Al (0.5:100 nm) shows maximum luminance of nearly 1400 cd/m(2) and a Commission Internationale de l'Eclairage chromaticity coordinates of (0.27, 0.30) at 12 V.
