چکیده مقاله
La3? doped ZnFe2O4 nanostructures were prepared
by the two-step sol gel method in the presence of
Zn(NO3)26H2O, Fe(NO3)39H2O, and La(NO3)3 in an
aqueoussolution. Besides, the effect of different type of surfactants
such as sodium dodecyl sulfate, cetrimonium bromide,
polyvinyl alcohol, oleic acid, and polyvinylpyrrolidone
on the morphology and particle size of final product was
investigated. Furthermore, the effect of La3? dope on the
magnetic properties of ZnFe2O4 nanostructures was investigated.
VSM results demonstrated the dope concentration play
an important role on the magnetic properties of final products.
According to the XRD results, the lattice parameter decreases
with added La3? from 8.443 to 5.5203 A ° , thus obeying
Vegard’s law. The products were characterized by XRD,
SEM, EDX, VSM, TEM, UV–visible, and EDS
