【摘要】 本文是作者1986年3月访问中国时的报告。文中介绍日本研究SERS(Surface enhan-ced Raman scatterjng)小组的最近成果。在实验方面,林(Hayashi)等人获得enhance--ment η接近SPP(surface plasmon ploariton)模型所予测的值;山田(Yamada)等人认为出现SERS现象中,化学吸附起着本质性的重要作用。理论方面,上羽(Ueba)等人应用(曲豆)(冫尺)(Toyozawa)等人的理论计算了:(1)允许少量电荷在表面连续能级和吸附分子激发状态之间转移的物理吸附系统共振;(2)电荷转移(CT)给Raman散射光强度及其光谱带来的影响。更多还原

【Abstract】 In this paper the recent achievements of Japanese SERS research groups are discussed. Experimentally, Hayashi et.al.obtained a value of η enhancement which approaches the value expected by the SPP modal; Yamada et.al.showed that chemical adsorption plays a substantial role in SERS phenomena. Theoretically, Ueba et.al.calculnted by using ( 1 ) the resonance of physical adsorption systems which permits small amount of electric charge transfer between the continuous surface levels and the excited states of adsorbed molecules; ( 2 )influence of CT(charge transfer) on the intensity and the spectrum of Raman scattered light.更多还原
