The analysis indicates that, when ¦Â-CD and PVA were used as templates, the formation of the lanthanum carbonate with particular morphologies has the same mechanism. For both cases, the lanthanum carbonate adsorbs, nucleates, and grows on specific radicals. At high temperatures, the difference in the energies of different surfaces of the lanthanum carbonate increases, leading to a one-dimensional growth. When the cotton was used as the template, the structural features of the cotton itself provide effective growth centers for the crystals, which form in the effective growth centers, leading to the lanthanum carbonate of particular morphologies. The lathanum carbonate prepared with organic compounds has better "phosphor-binding" effects than that prepared without organic compounds. Note: not sure about Á×½áºÏЧ¹û.

| Through analysis, ¦Â-CD and PVA as a template to form a special morphology of the mechanism of lanthanum carbonate is the same, are lanthanum carbonate group on a specific adsorption, nucleation, growth, high temperature, different crystal planes of lanthanum carbonate surface energy difference increase, so that crystal growth along one dimension; cotton as a template, the cotton itself, the growth of the crystal structure provides an effective center of the crystal in the center to form an effective, generating a specific topography of the carbonate La. |
