Milled Si nanoparticles were prepared by grinding with the beads of yttrium stabilized ZrO2 in enthanol and separated by the centrifuge. In order to estimate the effects on the pure Si nanoparticles from the thermal decomposition system, milled Si nanoparticles were heat-treated in the solution of dioctyl ether, stabilizers oleic acid and oleylamine. It was found that milled Si nanaparticles had irregular shape with a diameter of 4.2±1.6 nm and that the heat-treated ones were spherical with a larger diameter of 10.2±4.4 nm. Both they preserved the great monodispersion. Their structure, composition, morphology were characterized by the analyses of HRTEM, XRD and Raman scattering. These results revealed that the milled Si nanoparticles had the body-centered cubic structure, not only diamond structure like the bulk Si anymore. The stress from milling and the small size would reduce their crystallinity. After the heat treatment, the atoms of the milled Si nanoparticle would rearrange in the interior, and even combine with each other to form the better poly-crystalline Si nanopartcles. The ESCA analysis of milled Si and heat-treated Si nanoparticles exhibited the almost similar Si-Si binding energy despite a little increase from heat-treated one. The FTIR results indicated that there was a film consisted of SiO2 and ethanol molecules on the surface to prevent it from oxidation, and also proved there were not any stabilizers left on the surface of heat-treated Si nanoparticles. Moreover, when giving the specific wavelength of excitation, the specific PL spectra for the milled Si nanoparticles could be observed, so did heat-treated Si nanoparticles. The optical images and properties were also revealed from optical microscopy, the powder-PL analysis and the UV-vis spectrometer.
利用酒精与研磨锆珠，在适当研磨条件及离心后可得微小、表面不规则状之矽奈米粒子，平均粒径为4.2±1.6 nm；经过热处理之后，热处理矽奈米粒子之平均粒径会增至10.2±4.4 nm并呈球状结构，两者皆具有高度分散性；经高解析晶格、XRD、Raman分析可得研磨矽奈米粒子呈现体心立方结构，但受到研磨应力及粒径过於微小之影响，结晶性并不强烈；然而经热处理后，粒子与粒子结合，并使矽原子重新排列，结晶性有明显增加之趋势且形成多晶结构；透过ESCA与FTIR分析亦可得知，矽奈米粒子在热处理前后，其矽－矽键能值仅稍微增加，显示表面氧化比例稍为提升但大致维持矽－矽之键结，两者表面都具有二氧化矽及醇类溶剂分子薄层，如此可避免粒子向中心继续氧化，也证明表面未残留任何保护剂；在光学性质方面，利用PL分析得知研磨矽奈米粒子与热处理矽奈米粒子皆可在不同波长光源的激发下，激发出不同放光波长之特性光谱，萤光显微镜之照片及粉末PL分析亦可相互佐证之；此外，UV-vis光谱亦显示两者具有相同之吸收特性峰。
