Abstract

Abstract: Probe molecules of Tb(MAA)₃ Phen, Tb(Sal)₃ Phen and Tb(CA)₃ Phen were prepared by using terbium oxide (Tb₂O₃), methacrylate (MAA), salicylic acid (HSal), cinnamic acid (HCA) and phenanthroline (Phen). A series of temperature sensitive paints were obtained by the polymerization of different probe molecules, methyl methacrylate(MMA) and the initiator of benzoyl peroxide(BPO). The structure, morphology, luminescence property of probe molecules and the temperature quenching property of temperature sensitive paints were characterized by infrared spectrometer, fluorescence spectrometer and scanning electron microscopy. The effect of different ligands on the luminescence property of probe molecules and the temperature quenching property of temperature sensitive paints were studied. It is indicated that Tb³⁺ and primary ligands were coordinated and Phen was involved in. It is demonstrated that terbium with phenanthroline ternary complex of MAA as primary ligand has the best luminous performance. Temperature sensitive paints have favorable temperature quenching properties at the temperature range of 25-65℃ is illustrated. It is analyzed that the temperature sensitive paint based Tb(MAA)₃ Phen has a better application value comprehensively.

Key words: probe molecules, temperature sensitive paints, temperature quenching, terbium ions, phenanthroline
