摘　　要：作为贵金属纳米材料,纳米银在许多领域的广泛应用而成为当今纳米科学最感兴趣的研究对象。简单介绍了纳米银的合成方法如光化学法、超声辅助还原法、电化学还原法、模板法、辐射还原法和生物化学法,主要讨论了化学还原法和微乳液法以及纳米银合成研究的一些进展。光谱吸收是纳米银的重要性质,UV-Vis特征光谱是研究纳米银的形成和纳米晶生长的重要手段,因此详细评述了纳米银的光谱特性,最后,对它们的研究发展趋势进行了展望。Silver nanoparticles, as noble metallic nanomaterials, are of particular interest today because of their applications in many areas. Besides a brief introduction on the synthetic methods of silver nanoparticles, such as chemical reduction, photochemical method, ultrasonic-assisted reduction, electro-chemical method, template, irradiating reduction and biochemical method, the mini-review mainly discuss chemical reduction and microemulsion method as well as some research advances of the methods for preparation of silver nanoparticles. The characteristic absorption spectra are the important properties of silver nanoparticles, and the UV-Vis spectral researches are good for characterization of the formation and growth of silver nanocrystals. Thus, the UV-Vis spectral properties of silver nanoparticles are reviewed. The possible developing trends of the study on the synthetic methods and spectral properties of silver nanoparticles are also prospected.
