Nanostructured Sr-doped LaMnO3 were synthesized by facile hydrothermal method.
The XRD patterns of the LaMnO3 sample shows well crystallinity and phase purity with an
orthorhombic structure. The different morphologies of the LaMnO3 nanoparticles were
confirmed by field emission scanning electron microscopic (FESEM) images. The structural
properties were also confirmed by Fourier transform infrared (FTIR) and optical properties
were characterized by UV-Visible spectroscopy and Photoluminescence spectroscopy. Their
magnetic property has been analyzed by using vibrating sample magnetometer (VSM). All
these structural, morphological, optical and magnetic properties will be discussed in detail.
