Solid-state reaction is a prior method to synth esize some solid materials Solid phase benzoic acid and chloride of rare earth were used to prepare benzoic europium and benzoic terbium phosphors at room temperatureFT-IR spectra, TG-DTA curves and photoluminescence spectra of phosphors were determined.

With reference to luminescent mechanism of inorganic materials,Sr-Eu phthalate was prepared by blending Eu~(3+) into Strontium phthalate and low rare earth content luminescence had been achieved.

Study on the interaction between DNA and the complex of benzoic acid nitrogen mustard with Eu(Ⅲ) by the fluorescence method;
