Excitation functions of neutron, proton and α particle emission prior to scission measured in the reactions 28 Si+ 164,167,170 Er→ 192,195,198 Pb are studied using an extensive fission diffusion model and it is found that the model can well describe the trend of particle multiplicities of Pb isotopes measured experimentally as a function of the bombarding energy,which indicates the existence of isotope effects in prescission particle emission.

用推广的裂变扩散模型研究了2 8Si+16 4，16 7，170 Er→192 ，195，198Pb反应中测量的断前中子、质子和α粒子多重性的激发函数。发现扩散模型能很好地拟合这些轻粒子多重性随裂变系统激发能和Pb同位素的变化趋势。表明断前粒子发射存在一个同位素效应。进而在一个考虑了裂变过程中摩擦效应的统计模型的框架内，在In和Er这两个元素的同位素链中，考察了同位素效应与裂变碎片质量不对称性和裂变系统尺度的关系。计算结果表明：同位素效应的存在不依赖于裂变系统的大小和不对称性。此外，当裂变系统具有高的中质比时，轻带电粒子发射将不再敏感于裂变延迟时间的长短，而中子发射则非常敏感。

Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.

研究发现，氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响；醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面，使得氧化锌纳米点的表面缺陷和可见发射中心大大减少，因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强；氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用，使产物的发光性质得到改善。
