Effects of concentration of stabilizer (sodium dodecylsulfate: SDS) and ultrasonic irradiation power on the formation of gold nanoparticles (Au-NPs) were investigated. Au-NPs with multiple shapes and size were synthesized by controlling the concentration of stabilizer and ultrasonic irradiation power. The shapes and size of Au-NPs were controlled by changing either the ratio of Au(III) ion/SDS or the power of ultrasonic irradiation. The multiple shapes and size distribution of Au-NPs are dependent on not only the ratio of Au(III) ion/SDS but also ultrasonic irradiation power. The sonochemically synthesized Au-NPs were characterized by TEM and UV-vis spectroscopy.
研究了稳定剂（十二烷基硫酸钠：SDS）浓度和超声辐照功率对金纳米颗粒（Au-NPs）形成的影响。通过控制稳定剂浓度和超声辐照功率合成了具有多种形状和尺寸的Au-NPs。通过改变Au(III)离子/SDS的比例或超声辐照功率来控制Au-NPs的形状和尺寸。Au-NPs的多种形状和尺寸分布不仅取决于Au(III)离子/SDS的比例，还取决于超声辐照功率。通过透射电子显微镜（TEM）和紫外可见光谱对超声化学合成的Au-NPs进行了表征。
