溶液中稀土离子的发光水平的聚集是通过激发的非螯合有机分子的能量转移来实现的。二十一种芳香醛和酮已被证明能够将能量转移至 Tb3+ 或 Eu3+。这表明扩散控制过程对于转移是必要的，并且有机物的最低三重态会激发离子。简要考虑了作为激光材料的可能应用。
Population of luminescent levels of rare‐earth ions in solution has been accomplished through energy transfer from excited, nonchelated organic molecules. Twenty‐one aromatic aldehydes and ketones have been shown to be capable of transferring energy to Tb3+ or to Eu3+. It is suggested that a diffusion‐controlled process is necessary for transfer and the lowest triplet state of the organic excites the ion. Possible applications as laser materials are briefly considered.
