Green light-emitting organic material with narrow FWHM and high electroluminescence

A novel green emitting material of 2,4,6-Tristriphenylamine-1,3,5-s-triazine (TT3) was synthesized and the organic light-emitting diodes of indium tin oxide (ITO)/TT3/ biphasic calcium phosphate (BCP)/Mg:Ag based on TT3 as the hole transporting and emitting layer were fabricated. The electroluminescent properties were studied. The devices gave pure and bright green light emission peaked at 513 nm and the full width at half maximum of the emission was narrowed by 13.2% compared with the typical green EL device of ITO/TPD:PVK/tris(8-hydroxyquinolinato)aluminium/Mg:Ag, and the brightness was higher than that of the typical device at the same voltage.
