Cu)colloid were synthesized by Sol-Gel method and their optical properties were studied by UV absorption spectra
PL and EL spectra.The size of particles is approximately 3~4nm deduced from absorption spectra.PL spectra show emission band of the corresponded doping center
which come from absorption of ZnS host.EL devices of ZnS:
TM
(
TM
=Mn
Cu)nanoparticle were fabricated by spin-coating method
the turn-on voltage and EL intensity with operating voltage were measured.A probable explanation was given for the PL and EL properties.
