傅里叶变换表面等离子体共振频率对金膜表面溶液折射率响应
Responses of Fourier Transform-Surface Plasmon Resonance Frequency to Refractive Index of the Solution in Contact with the Gold Film
摘要
Abstract
By using the fourier transform-surface plasmon resonance ( FT-SPR) technique, the FT-SPR responses (R) toward NaCl, KC1 and ethanol with various aqueous concentrations were measured. A quantitative equation of R = 1. 53 × 105 (n - 1. 3333) was set up for the response toward the concentration dependent solution refractive index ( n). The result shows that the FT-SPR response of 15 cm -1 is obtained upon 0. 0001 change in the refractive index. This equation is promising in direct measurement of refractive index of unknown media.关键词
