N2 - Metal oxide nanoparticles are usually synthesized using chemical materials that harmful for the environment. In this research, neodimium oxide nanoparticles (Nd2O3 NPs) has been green synthesized by a facile and eco-friendly method using aqueous extract of Terminalia catappa leaf (TLE) as weak base source and Nd(NO3)3 as precursor. Phytochemical test of TLE showed the presence of flavonoid, alkaloid, polifenol and saponin. The formation of Nd(OH)3sol was observed by UV-Vis spectrophotometer. Nd(OH)3 gel was heated and calcined to obtain Nd2O3 NPs. Functional groups of TLE and Nd2O3 NPs were characterized by Fourier transform infrared (FTIR) spectroscopy. The crystal structure and particle size of Nd2O3 NPs were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). UV-Vis spectrophotometry data were obtained to investigate the shift of wavelength and absorbance value. These are due to the interaction of hydrolysis reaction from alkaloids and Nd(NO3)3 to form Nd(OH)3. The dispersion of Nd2O3 NPs in water showed an increasing wavelength due to the effect of nanoparticle size. The characterization of UV-Vis-DRS was conducted to obtain the energy band gap of Nd2O3 NPs as 4.4 eV, with maximum wavelength, λmax 378 nm. Peak of TLE was broad and strong occurred at 3261 cm-1 as -OH group vibration, 1694 cm-1 as C=O group, 1359 cm-1 as -NH group, and 1056 cm-1 as C-O group. All of the data showed the functional groups of secondary metabolites in TLE. Spectrum of Nd2O3 NPs occurred at 423 cm-1 as Nd-O bond vibration. The crystalline phase of Nd2O3 NPs was determined by XRD, which has conformity with the characteristic peaks of Nd2O3-A as hexagonal phase (JCPDS No. 0282). Particle size of Nd2O3 NPs using TEM was observed at approximately 40-60 nm.
