Abstract
A new DCM derivative containing the phenoxazine moiety (DCPXZ) has been synthesized for use as a red fluorescent dye molecule in organic light-emitting diodes (OLEDs). The photoluminescence and electroluminescence properties of DCPXZ were examined. The maximum photoluminescence of DCPXZ in chloroform solution (10â5 mol) was observed at 616 nm. EL devices were fabricated with the structure ITO/PEDOT-PSS/Cu-PC(15 nm)/α-NPD(45 nm)/Alq3:DCPXZ(30 nm)/Alq3(30 nm)/LiF(0.5 nm)/Al. The maximum EL emission for the 2.0% DCPXZ-doped device was at 608 nm with CIE coordinates (0.57,0.42). The EL device exhibited a maximum brightness of 15,000 cd/m2 at 19.4 V and a power efficiency of 1.04 lm/W at a luminance of 100 cd/m2.
