摘要/Abstract

摘要： 研究了不同光源、光照时间、反应物浓度等对绿色银胶形成的影响,分别制备了绿色银胶和黄色银胶.透射电镜显示,它们的平均粒径分别为100nm和40nm.绿色银胶在393.9nm和713.3nm处有两个吸收峰;黄色银胶在419.3nm处有一较宽的吸收峰.它们的最强共振散射峰位于470nm处;绿色银胶在340nm和80nm还有两个小共振峰.

关键词: 绿色银胶, 黄色银胶, 光化学法, 共振散射光谱

Abstract: The green silver colloid and yellow silver colloid were prepared by two-step photochemical procedure and UV photochemical procedure respectively. Their sizes measured by TEM are 100 nm and 40 nm respectively. The green silver solloid exhibits two absorption peaks at 393.9 nm and 713.3 nm , The absorption peak of yellow silver colloid is at 419.3 nm. They have a maxium resonance scattering peak at 470 nm, and the green silver colloid has other two resonance scattering peaks at 340 nm and 680 nm.

Key words: green silver colloid, yellow silver colloid, photochemical procedure, resonance scattering spectroscopy
