Synthesis of complex compounds of 2-(methylamino) benzoic acid (L) with ions of samarium (III), europium (III), terbium (III), gadolinium (III) and dysprosium (III). According to elemental analysis and thermogravimetry, the complexes obtained are hydrates of the composition LnL3 • nH2O, where n = 1-5. The area of their thermal stability ranges from 100 ° C to 240 ° C. Electronic and infrared absorptionspectra of the ligand and complexeswith rare-earth metal ions were measured. According to the IR spectra, coordination of the ligand with the metal ion is carried out on the carboxyl group. The carboxyl group is coordinated bidentately. A mercury lampwith a wavelength of 248 nm was used to excite the luminescence. The highest luminescence intensity is observed for the coordination compounds Eu3 +, Tb3 +, and Dy3 +

Phase Selectivity

All solid solutions (EuxY1−x-PTC, x = 0.013–0.82) are isomorphic to Eu-PTC, but different from Y-PTC, and show phase selectivity as well as excitation wavelength dependent emission.
