| Summary: | <p>Abstract. We have developed an optical resonance system for observing the surface<br />
plasmon resonance (SPR). The SPR was successfully generated via a glass prism<br />
coupler in a Kretschmann configuration where the gold (Au) thin f1lm was<br />
thermally evaporated on the prism base. As a light source, a typical He-Ne laser<br />
with wavelength 632.8 nm was used to observe the SPR phenomenon. The angular<br />
scan in the attenuated total reflection (ATR)spectra shows the intensity drop (dip).<br />
That clearly indicates the SPR coupling phenomenon in the interface Au thin film.<br />
Some spectra of various Au thiclr..ness were also shown with identical angular<br />
positions of the dips.</p> |
