Abstract: 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.

Abstract: Microwave driven hydrothermal synthesis and hydrothermal synthesis were used to obtain ZrO2 nanopowders. Their production with varying phase composition, the characterisation and selected optical properties concerning their potential use as luminescence oxygen sensors are reported. It was found that the powders obtained by the microwave driven hydrothermal method and annealed at 750 0C in air show experiment repeatability within an accuracy of 6 %.
