Abstract

Using 4,4'4"-tris(N-carbazolyl)-triphenylamine (TCTA) small molecule interlayer, we have fabricated efficient green PHOLED by solution process. The maximum current and power efficiency values of 33.7 cd/A and 19.6 lm/W are demonstrated, respectively. Results reveal a way to fabricate the PHOLED using TCTA interlayer by solution process, promising for efficient and simple manufacturing.
