乔治亚理工学院的研究表明：由2~8个银原子组成的银纳米团能够成为一种新型光学储存介质的基础。来自纳米团的荧光辐射也有潜力用于生物学标签和电光显示。这类纳米材料具有一个新性能：就是将波长不到250nm的蓝光照在这种材料上，它便能发出荧光。也就是说，用较长波长的光照
Georgia Institute of Technology research shows that: from 2 to 8 silver atoms silver nanocomposite can become a new type of optical storage media basis. Fluorescent radiation from nanoclusters also has potential for biological labeling and electro-optic display. This kind of nano-material has a new performance: it is the blue light of less than 250nm wavelength in this material, it will be able to emit fluorescence. That is, use longer wavelengths of light
