Synthesis, Characterization And Application Of Binary And Ternary Rare Earth Complexes With Camphoric Acid And 1, 10-Phenanthroline Doped In Siliga Glass

Binary and ternary complexes of rare earth ions (Eu3+,Tb3+)with camphoric acid and 1,10-phenanthroline have been synthesized and characterized by elemental analysis, 1HNMR, IR,FT-Raman. The composition of complexes have been confirmed to be Eu2(CA)3 2H2O , Tb2(CA)3-2H2O ,Eu2(CA)3(phen)2,Tb2(CA)3(phen)2.(CA: camphoric acid, phen: 1,10-phenanthroline), the spectroscopic properties have been discussed. Afterwards, ternary Eu3+ complexes.binary Tb3+ complexes having better fluorescence intensities were incorporated in SiO2 glass using sol-gel process with appropriate treatment.The fluorescence of Eu3+(Tb3+)-doped silica glasses were measured. The result showed that the optimum excitation wavelength of Eu3+ was 393nm,the strongest emission wavelength was 615nm; the optimum excitation wavelength of Tb3+ was 245nm,the strongest emission wavelength was 545nm. Through comparing with rare earth complexes incorporated in Si02 glass at different annealing (200癈 and 800癈 ) the luminous intensity under these two kinds of situations, draw the conclusion: 1 .When the form of mixing the rare earth (Eu3+, Tb3+) is the same, the positions of the launch influence basically wasn't changed. 2. But when the condition of prepariation was different, the fluorescences emission intensity of all kinds of silican glass were different. When 254nm light and 245nm light were used as excitation wavelength , under 8000C annealing the silican glass- doped Eu2(CA)3(phen)z and Tb2(CA)3 2H2O had the most heavy fluorescences intensity.
