本文用微乳液法合成了不同表面活性剂包覆的和反应物阴阳离子配比不同的纳米Bi~2O~3有机溶胶。发现阴阳离子配比对纳米体系的发光有很大影响, 不同的表面包覆剂对发光的影响则较小, 并对此进行了解释。

Nanometer-sized Bi~2O~3 organosols with different interfacial coatings and cation/anion ratios were synthesized through microemulsion method. It was found that cation/anion ratios have more significant effects on the luminescence of organosol system than the properties of surfactant do. This phenomenon was explained.

Key words: SURFACTANTS, LUMINESCENT MATERIALS
