A Tb (III) ternary complex luminescent material has been synthesized and characterized by infrared spectrum. The luminescent properties of Tb (III) luminescent material were studied in solid and in ethanol, methanol and DMSO solutions. The effect of solvent factors and the doping different concentration of Ca (II) ion on the fluorescence intensity of Tb (III) complex luminescent material were tested. The results show that both the solvents and the doping different concentration of Ca (II) ion could quench the luminescent intensity of Tb (III) complex luminescent material.
