“…Rare earth oxides and their mixed oxides are useful materials with luminescent, catalytic, electric, and magnetic properties. Lanthanum, the lightest element in the lanthanide series [22] , is insoluble in iron, but has an affinity for oxygen. Pasebani, et al observed the incorporation of lanthanum oxide into the matrix; they milled Fe-5% La2O3 for 10 h, they have proved that during milling, only the peaks of iron [19] .…”

Fe-10wt% La (OH)3 composite powders have been fabricated by ball milling, under argon atmosphere for milling periods of 0, 5 and 10 h, respectively. Changes in structural, morphological, thermal and magnetic properties of the powders during mechanical alloying and during subsequent annealing have been examined by X-ray diffraction, scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and vibrating sample magnetometer (VSM). XRD results: showed the formation of new phases (Fe and LaFeO3 perovskite) created through the ball milling. The results showed that the crystalline size of ball milled powders decreased with increasing the milling time. In fact, after 10 h of ball milling, La (OH)3 changes from nanostructure in amorphous structure. The magnetic measurements display a distinct saturation magnetization and coercivity.

The simple hydrothermal approach was used to create various morphologies of cerium (Ce) substituted lanthanum oxide (La2O3) nanostructures, with a reaction time of 6 h at 100 °C. The research on Ce‐substituted La2O3’s morphology, particle size, band gap, and photocatalytic efficacy are affected by calcination temperature. The powder X‐ray diffraction pattern of Ce‐added La2O3 nanoparticles reveals their hexagonal shape. Field emission scanning electron microscopy is used to study the morphology of freshly produced nanoparticles. The elements in the synthesized and calcined samples were proven to exist by energy dispersive X‐ray analysis. La2O3 samples synthesized at room temperature and calcined at 300 and 600 °C are calculated to have band gap energies of 3.1, 3.0, and 2.9 eV, respectively through UV–visible spectroscopic analysis. The photoluminescence's analysis yields the exactness in activity of photo‐catalyst. It's possible to match the broad peak around 439 and 1045 cm−1 with the O─H vibration.
