We present the synthesis of lanthanum nitrate nanoparticles via the polyol method. A crystallographic study of La(NO3)3 4H2O nanoparticles was carried out using the Rietveld method and XRD to detect the phases of the yield: (monoclinic) and β (orthorhombic) phases were obtained. Thermogravimetric analysis showed a unique dehydration process in the 65 °C-245 °C temperature range and a dehydroxylation phase in the 333 °C-558 °C temperature range. Using TEM-EDX, and DLS, the purity of the material was evaluated; a spherical shape morphology and monodispersity were observed. The absorbance at 1340-1440 cm−1 and 1500-1600 cm−1 (IR regions) of the lanthanum nanoparticles was deconvolved to increase the resolution of the chemical imprint in these regions.
