稀土有机配合物发光及光声光谱研究方法

Photoacoustic Spectroscopy Study Method on Fluorescence of Rare Earth Complexes

简要综述了稀土有机配合物发光研究的进展。光声光谱从无辐射的新角度对这一领域进行研究，结果表明：光声光谱能简便而有效地反映稀土离子的能级状况，确定能级的荧光性质，根据光声光谱的振幅和位相谱，可了解稀土配合物发光的能量传递和弛豫途径。

Advance in luminescence of rare earth complexes is briefly summarized. New views from nonradiative transition is proposed by photoacoustic spectroscopy (PAS) to study luminescence of rare earth complexes.PAS can be used to determine fluorescence property of rare earth energy levels.Energy transfer and relaxation channel would be understood by PA amplitude and phase spectra.
