“…Equation (1) shows the dependence of the Raman line intensity on the frequency of the scattered light. When the laser line is far removed from the corresponding frequency of the electronic transition u,, u, -u >> 0, a typical u: dependence of the analytical signal is obtained, and blue laser lines are more efficient than red laser lines.…”

Silver island films are shown to be stable under normal laboratory conditions, and easy to use as optical sensors for the detection of traces of tetrasulphonated copper phthalocyanine. The surface-enhanced Raman (SER) effect is used in conjunction with a resonance Raman (RR) increase in the analytical signal to levels that allow the detection of nanogram amounts. The relative intensities of characteristic group frequencies do not seem to be altered by the SER enhancement mechanism.

An etched polymer was evaluated as a substrate suitable for routine SER analysis and was found to perform similarly to crossed gratings and posted quartz wafers. Silver particles were layered onto sheets of etched poly(ethylene terephthalate) by chemical reduction, sputtering, and vapor deposition. Enhancement factors ranged from 10(4) to >10(5) for crystal violet on chemically reduced and sputtered surfaces, respectively. Ranges of linearity up to 3 orders of magnitude were attained with limits of detection of ∼5 pg. The variability of response was <20% RSD for both routinely and painstakingly prepared samples. To induce enhancements beyond those possible from the dry substrate, a thin film of water was held on the analyte-treated substrate surface in a liquid state. Typical spectra of nine analytes with amino, carboxylate, and/or nitro groups were collected from the most active substrate.
