gold colloidal meaning in Chinese

放射性胶体金

We also report the uv - visible optical absorption spectra of these colloids . to the metal plate prepared simultaneously , the measurement result of sem and afm of this plate is also reported and the roughness of the silver plate surface is about 60nm . both the colloids and the nano - scale metal surface can become the very perfect sers substrates . rhodamine b , a kind of strong fluorescence laser dye , with gold colloidal surface , has been studied by surface - enhanced raman spectroscopy ( sers ) with near - infrared ( nir ) excitation in the presence of the halide ions ( cf , br - , f )
利用透射电子显微镜( tem ) ，对胶体粒子的尺寸大小及形态进行了观测，表明这些胶体为粒径介于5 35nm的纳米体系，并对该胶体体系进行了紫外?可见吸收光谱的研究；在制备出金属胶体的同时，经过激光照射后的金属表面为纳米量级的粗糙表面，对该表面进行了扫描电镜( sem )及原子力显微镜( afm )的测量，结果显示该表面的粗糙度平均为60nm 。
