将稀土配合物Eu（hfa）3（phen）分散在对氯苯酚和表面活性剂AOT自组装的有机凝胶中。从复杂的有机凝胶系统中观察到的发射强度的时间曲线表明，可能产生放大的受激发射时，激发强激发脉冲。作为主体材料，有机凝胶可以支持8倍的配合物沿着具有更好的发射量子产率。对复合有机凝胶的激光增益因子的理论估计也表明该系统可能在激光系统中有应用。
The rare-earth complex Eu(hfa)3(phen) is dispersed in the self-assembled organogel ofp-chlorophenol and surfactant AOT. The time profiles of the emission intensity observed from the complex–organogel system suggest the possible generation of amplified stimulated emission when excited with a strong excitation pulse. As the host material, the organogel can support eight times as much of the complex along with better emission quantum yield. A theoretical estimation of the laser gain factor of the complex–organogel also suggested that this system might have application in laser systems.
