采用超分子组装法制备了一种具有刺激响应性的镧系智能纳米复合材料，并将其作为一种活性材料应用于多维记忆材料中。镧系元素络合物与碳量子点的缀合提供了基于配体能级的调制的刺激响应，并提供微秒至纳秒的荧光寿命，从而在空间和时间维度上产生有趣的记忆性能。本研究为基于无机-有机杂化纳米系统的多维存储材料的未来发展指明了新的方向。
A stimuli-responsive lanthanide-based smart nanocomposite has been fabricated by supramolecular assembly and applied as an active material in multidimensional memory materials. Conjugation of the lanthanide complexes with carbon dots provides a stimuli response that is based on the modulation of the energy level of the ligand and affords microsecond-to-nanosecond fluorescence lifetimes, giving rise to intriguing memory performance in the spatial and temporal dimension. The present study points to a new direction for the future development of multidimensional memory materials based on inorganic-organic hybrid nanosystems.
