¢º Luminescence Spectroscopy
Research interests in this laboratory have been primarily concerned about chemical kinetics and molecular spectroscopy of small molecules in the gas phase, and we are attempting to apply a similar technique to a solution phase. One of our recent research interests is concerned about the luminescence studies of lanthanide(III) complexes in solution. Because of its characteristic electronic structure of Eu3+ and Tb3+ ions, the shapes of excitation and luminescence spectra as well as the luminescence lifetimes observed from complexes formed with these ions provide a valuable information on the local structure of the active site of the biomolecules in solution. For this purpose, a tunable pulsed laser with narrow line width is employed to investigate excitation and luminescence spectra of the lanthanide(III) complexes, and a time resolution technique is used to measure luminescence lifetimes.
