Complex Material

A new Tb (III) complex material was synthesized from Tb(NO3)3•6H2O and 1-acetyl-2-naphthol-4, 4'-diaminodiphenyl ether. The infrared characterization and luminescent properties of the Tb (III) complex material were studied. Based on the fluorescent property, the Tb (III) complex material can only emit the fluorescence of the ligand, but not emit the characteristic fluorescence of Tb (III) ion in solid and in organic solvents. This indicates that the energy transfer process between the ligand and Tb (III) ion is ineffective.

AbstractPhotoluminescence (PL) of SiO2 films co-doped with Si nanocrystals (nc-Si) and Er was studied. The average size of nc-Si was changed in a wide range in order to tune the exciton energy of nc-Si to the energy separations between the discrete electronic states of Er3+. PL from exciton recombination in nc-Si and the intra-4f shell transition of Er3+ were observed simultaneously. At low temperatures, periodic features were observed in the PL spectrum of nc-Si. The period agreed well with the optical phonon energy of Si. The appearance of the phonon structures implies that nc-Si which satisfy the energy conservation rule during the energy transfer process can resonantly excite Er3+. The effects of the quantum confinement of excitons in nc-Si on the energy transfer process are discussed.
