Abstract
In this paper, a method was proposed for the synthesis of one-dimensional nanoparticles based on new rare earth (RE) compounds, RE hydroxyglycinates. One-dimensional nanoparticles were obtained by the interaction of RE oxides (Y2O3, Eu2O3, Ho2O3, Er2O3, Gd2O3, Sm2O3) with glycine solutions at the molar ratio NH2CH2COOH : RE2O3 = 35 : 1 at 60°C. The thickness of nanoparticles was 50–150 nm and the length was 1–5 μm. FT-IR and Raman spectroscopy, thermal analysis and CHN elemental analysis data allowed to establish that the composition of the hydroxyglycinate nanorods is described by the formula Ln(NH2CH2COO)1.2(OH)1.4(CO3)0.2·1.2H2O. Based on atomic force microscopy data, the Young’s modulus of one-dimensional europium hydroxyglycinate nanoparticles was determined (~35 GPa) and the lower limit of the shear modulus was estimated (\( \gg \)2.0 GPa).
