| Abstract: | A zinc(II)
complex with 5-chloro-8-hydroxyquinoline has been used as emitting material to
produce yellow light. On excitation by UV light at 385 nm, thin film of the
complex fluoresced at
550 nm. Multilayer organic electroluminescence devices fabricated using this
fluorescent material produce emission with good chromaticity (CIE coordinates x
= 0.313 and y = 0.576).
Maximum luminance of 466 cd/m2 is achieved when
2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane is used as dopant in
4,4-bis[N-(1-naphthyl)-N-phenyl-amino]biphenyl at
12 V. The devices show typical non-linear
diode current-voltage characteristics under forward bias with the threshold
voltage of 6V. The CIE coordinates are found to be independent of the
operating voltage. |
