| 摘 要： | 研究了铽配合物Tb(m-MBA)3phen]2·2H2O与PVK共掺杂体系的激发光谱和光致发光谱, 发现两者之间存在着能量转移，由于PVK的发射光谱和铽配合物的激发光谱重叠很小，两者之间发生Frester能量传递的几率很小，铽的发光主要是由于铽配合物的配体俘获了电子-空穴对使配体受到激发而导致的，在电致发光中, PVK的发光完全被抑制, 与光致发光的表现不同, 这是由于两种发光(光致和电致)机理不同造成的。

| Abstract: | Excitation and photoluminescence(PL) spectra of the mixture terbium complex and PVK were investigated. The excitation spectrum of Tb complex dispersed PVK film is very similar to that of the pure PVK film, indicting that energy transfer occurs from PVK to Tb complex. For the overlap between the excitation spectrum of Tb complex dispersed PVK film and the PL spectrum of PVK film is very little, the ratio of occurrence for Frester energy transfer is very little. The emission of Tb3+ mainly comes from the excited ligand，which comes from the ligand capture of electron-hole pairs. In the electroluminescence(EL) spectra, the emission of PVK is completely restrained and only emission of Tb3+ is occured, which origins from the different mechanism in comparison with photoluminescence. |
