Tb (oct-phe)3·H2O and Eu (oct-phe)3·H2O were prepared by chemical reaction in solution. The molecular formula of the complex was determined by elemental analysis and FT-IR. The optical properties of rare earth complexes were further tested by ultraviolet-visible-infrared absorption measurements. The results show that the optical absorption performance is better in the wavelength range of 200-300 nm. The luminescent properties of the rare earth complexes in the wavelength range of 450-750 nm were tested. It was found that the rare earth (Eu, Tb) complexes of octylphenylalanine have good luminescent properties.

The 2-carboxybenzaldehyde-1H-benzotriazol-1-aceylhydrazone (C16H13N5O3) has been synthesized and used in preparing thirteen novel rare earth complexes. The complexes were characterized by elemental analysis, FT-IR, and UV-Vis, and the formula is RE (C16H11N5O3)·NO3·xH2O·yC2H5OH (RE=La, Ce, Pr, Nd, Sm, Eu, Tb, Ho, Er, Yb) and RE(C16H12N5O3)2·NO3·5H2O (RE=Gd, Dy, Y) .The thermal decomposition processes of the thirteen complexes were studied by thermal gravimetric technology and their apparent activation energy values were calculated by Kissingers and Ozawass method.

AbstractThe heating behavior and effect of experimental parameters like holding time, calcination temperature and microwave power on the weight loss of the mixed rare earth carbonate using microwave heating have been studied, also characterized by X-ray diffraction, thermogravimetry-differential scanning calorimetry, scanning electron microscopy (SEM), particle analysis and Fourier transform infrared (FT-IR). The results show the following: rare earth oxides are obtained at 850°C for holding 1 h; FT-IR analysis indicates that the vibration absorption peak of carbonate disappears after calcination using microwave, confirming the feasibility of microwave calcination for the rare earth carbonates; SEM shows that the rare earth oxides have the characteristics of better and finer particles, have better dispersion and have surface that is more loose and porous than that of products using conventional calcination; particle analysis indicates that average size (D
