摘要

研究了六硼化镧(LaB6)纳米粒子在水中和溶胶-凝胶二氧化硅中的分散。在有和没有柠檬酸的水中,六硼化镧纳米颗粒/团聚体的平均尺寸随着zeta电位的增大而减小。将柠檬酸盐包被的LaB6纳米粒子冷冻干燥,用TEOS/乙醇/水/盐酸混合,使纳米粒子分散在溶胶-凝胶二氧化硅中。提出了柠檬酸盐包覆LaB6与二氧化硅相互作用的模型。

Dispersion of lanthanum hexaboride nanoparticles in water and in sol-gel silica arrays
Dispersion of lanthanum hexaboride (LaB6) nanoparticles in water and in sol-gel silica was investigated. The average size of lanthanum hexaboride nanoparticles/agglomenties decreases with increasing magnitude of the zeta potential in water with and without citric acid. Citrate-coated LaB6 nanoparticles were freeze-dried and mixed with TEOS/ethanol/water/HCl to disperse the nanoparticles in the sol-gel silica. A model for the interaction of citrate coated LaB6 and silica is presented.
