Abstract:
Light emitting diodes have always gained high interest to their
potential for high efficiency lighting. Fabrication of Sb2Se3/ZnS coreshell
nanowire LED is reported for first time. In this report
Sb2Se3/ZnS core-shell nanowire synthesis by hydrothermal method
and this composition was spin coated on FTO substrates to make thin
films. UV visible spectroscopy, Photoluminescence spectroscopy and
X-ray diffraction techniques were used to characterized thin films of
Sb2Se3/ZnS core-shell composition. UV visible spectroscopy showed
that the absorption spectrum of Sb2Se3/ZnS core-shell thin films was
in UV region and photoluminescence spectroscopy showed that the
emission spectrum is in visible and infra-red region. X-ray diffraction
(XRD) was used to determine crystalline structure and phases within a
solid. For device fabrication NiO and ZnO were used as hole transport
layer and electron transport layer respectively. Sb2Se3/ZnS core-shell
nanowires were sandwiched between hole transport layer and electron
transport layer. Device was characterized by electroluminescence
spectroscopy and IV measurements.
