Room-Temperature Synthesis of Multi-Morphological Coordination Polymer and Tunable White-Light Emission

The multi-morphological coordination polymer La(1,3,5-BTC)(H2O)(6) has been prepared through simple and mild one-step approaches at room temperature on a large scale (1,3,5-BTC = 1,3, 5-benzenetricarboxylate). The delicate sheaflike, broccolilike, urchinlike, and fanlike hierarchical architectures made of uniform nanorods were obtained through splitting crystal growth. More interestingly, these three dimensional architectures can exhibit tunable white-light emission by codoping Tb3+ and Eu3+.
