Preparation And Properties Of Temperature Sensitive Paint Based Phenanthroline Ruthenium Complexes

In this thesis paper,using RuCl3, Rare earth chlorides, phenanthroline as raw materials, the luminescent probe molecules Ru(phen)3Cl2、Ru1-xGdx(phen)3Cl2、Ru1-xNdx(phen)3Cl2, were obtained. The probe molecules are doped into the poly (methyl methacrylate)(PMMA), access to the Ru(phen)3Cl2/PMMA,Ru1-xGdx(phen)3Cl2/PMMA, Ru1-xNdx(phen)3Cl2/PMMA TSP. The structure and properties of prepared probe molecules samples were examined by scanning electron microscope, infrared spectrum, ultraviolet absorption spectra and fluorescence spectrum. The infrared spectrum showed that the structure of phenanthroline were not destroyed. Ultraviolet absorption spectra showed that the absorption band of the probe molecule is339-495nm. Fluorescence spectrum of TSP sample showed that the emission peak of the sample was586nm when the TSP was excited by444nm.In addition,the emission strength of the TSP was decreased with the increasing of temperature, it showed that TSP has good temperature quenching property.
