| Description |
Samarium(Sm)-doped ceriumoxide (CeO2)
thin films were fabricated using electron beam evaporation
technique. The synthesized films were deposited
either on glass or ITO substrates and studied their nature
by annealing at different temperatures. The optical
properties and other morphological studies were done
by UV–Vis,XRD,XPS, SEM, EDS, and FT-IR analysis.
XRD and XPS analysis clearly confirm the presence of
Sm in the ceria site. From the SEM study, it was found
that after annealing at high temperature (*300 or
500 �C), the particles sizewas reduced due to breakdown
of large aggregates of particles which is also confirmed
from UV–Vis, XPS, andXRDanalyses. The FT-IR study
proves the presence of –COO–, –OH, or ammonium
group on the particles surface. The deposition of Smdoped
CeO2 nanomaterials was found more feasible on
ITO substrate compared to that of glass substrate in terms
of stability and depth of film thickness. The Sm-doped
CeO2 nanomaterial acts as a re-usable catalyst for the
reduction of organic dye molecules in the presence of
NaBH4. The catalysis rate was compared by considering
the electron transfer process during the reduction. The
synthesized Sm-doped CeO2 thin films might find wide
variety of applications in various emerging fields like
solid oxide fuel cells (SOFCs), oxygen sensor or as
catalyst in different types of organic and inorganic
catalytic reactions. The fabrication process is very
simple, straightforward, less time consuming, and cost
effective
