resonance shift
解釋
共振位移-
The absorption characteristics was that the surface plasma absorption peak appeared around 570 nm shifted to a short wavelength and strengthened as the cu composition increased. but the maximal shift range of the absorption - edge preponderated over 500 nm, and leaded that the dipolar plasma resonance absorption peak were covered up and gradually disappeared in the absorption spectrum. we theoretically explained the mechanism of the modulating action
