在前人对镧系和锕系离子的研究中，对水化Am3+的发光进行了详细的研究。根据观测到的发射光谱和激发光谱，确定水态Am3+的发光态为5D1。在295 K下，Am3+在H2O溶液中的发光寿命为（22 +/- 3）ns，在D2O溶液中的发光寿命为（155 +/- 4）ns。judd - offelt跃迁强度理论定性地描述了观察到的Am3+相对积分荧光强度。本文综述了近年来络合三价f元素离子在溶液中的发光研究，比较了镧系离子4f态与锕系离子5f态性质的异同。
Detailed studies of the luminescence of aquated Am3+ are presented in the context of prior work on lanthanide and actinide ions. The luminescing state of aquated Am3+ is confirmed to be 5D1 based on observed emission and excitation spectra. The luminescence lifetime of Am3+ in H2O solution is (22 +/- 3) ns and (155 +/- 4) ns in D2O solution at 295 K. Judd-Ofelt transition intensity theory qualitatively describes the observed Am3+ relative integrated fluorescence intensities. Recent luminescence studies on complexed trivalent f-element ions in solution are reviewed as to the similarities and differences between the lanthanide ion 4f state and the actinide ion 5f state properties.
