Abstract

Using(E)-2-(4-(diphenylamino)styryl)quinolato-zinc (TPAHQZn) as a hole-transporting emitter

a yellow OLED was fabricated with the molecular structure: indium-tin oxide(ITO)/ 4

4-{N

-(2-naphthyl)-N-phenylamino}-triphenylamine (2T-NATA)(15 nm)/ (E)-2-(4-(diphenylamino)styryl)quinolato-zinc (TPAHQZn)(

nm)/9

10-bis(2-naphthyl)anthracene(ADN)(31 nm)/ tris(8-quinolinolato) aluminum(Alq

)((65-

) nm)/LiF(0.6 nm) /Al. By adjusting thicknesses of TPAHQZn

a yellow OLED was obtained which has the maximum luminous efficiency of 0.84 cd /A (at 10 V) and maximum luminance of 2 479 cd /m

(at 14 V). The device emits pure yellow light efficiently and stably

the Commission Internationale De LEclairage (CIE) coordinates slightly varied from (0.502

0.449 5) (6.346 cd/m

at 8 V) to (0.497 9

0.453) (2 479 cd/m

at 14 V).
