Ultrasound-Induced Morphology Transformation from 3D Microspheres to 1D Nanorods of Luminescent Coordination Polymer
Abstract:Hierarchically spherical architectures self-assembled by nanorods of coordination polymer La(1,3,5-BTC)(H2O)6:Dy3+ have been successfully prepared on a large scale via rapid static growth in solution phase at room temperature. Interestingly, these uniform and well-dispersed 3D microspheres are sensitive to ultrasound, which can be completely transformed into 1D nanorods through simple ultrasonic treatment. The photoluminescence properties of the nano/microstructured La(1,3,5-BTC)(H2O)6:Dy3+ are also investigated in detail, indicating that the obtained lanthanum 1,3,5-benzenetricarboxylate is a new promising host material for the luminescence of Dy3+ ions.
