Findings from Johannes Kepler University Provide New Insights into Aromatic Polycyclic Hydrocarbons

February 28, 2014



By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Aromatic Polycyclic Hydrocarbons. According to news reporting originating from Linz, Austria, by NewsRx correspondents, research stated, "In this paper, we report on the Prod."

Our news editors obtained a quote from the research from Johannes Kepler University, "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."

According to the news editors, the research concluded: "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."
