Characterization of Optical and Electronic Properties of (N, N’-bis(salicylidene)-ethylenediamine)zinc as an Organic Electroluminescent Materials
was synthesized and characterized. Zn(salen) exhibits high thermal stability
excellent thin film forming ability. Its HOMO
LUMO and electrochemical band gap were estimated to be-5.87 eV
-3.41 eV
and 2.46 eV by cyclic voltammetry
respectively. Zn(salen) powder exhibits bright blue emitting
but Zn(salen) film exhibits yellow emitting under radiation of 365nm. The device ITO/CuPc/NPD/Zn(salen)/Al could emit yellow light. The EL peak was at about 552 nm with CIE coordinates of
x
=0.504
y
=0.316. The device has a turn-on voltage of about 7.5 V and a maximum brightness of about 301 cd/m
