Synthesis and optical properties of europium pentafluoropropionate 1,10-phenanthroline complex and its silica glass
Europium pentafluoropropionate 1,10-phenanthroline complex, Eu(C2F5COO)3$Phen (Phen =1,10-phenanthroline), were synthesized and characterized by elemental analysis, Fourier transform infrared spectroscopy (FT-IR), photoluminescence (PL) spectroscopy and thermogravimetric analysis (TA). At the same time, its silica glass was synthesized by in situ processes. The excitation spectra of the complex demonstrate that the energy collected by “antenna ligands” was transferred to Eu3+ ions efficiently. The room-temperature PL spectra of the complexes are composed of the typical Eu3+ ions red emission, due to transitions between 5D0->7FJ(J = 0->4). The decomposition temperature of the complex was 290°C, which indicates the host complex is quite stable to heat. Then the affection of anneal temperatures on PL properties of SiO2 glass were studied. The PL intensity of the SiO2 glass annealed at 160°C was higher than other annealed temperatures for 24 h in air.
