Selecting an Excitation Wavelength for Raman Spectroscopy
Here, we examine the problem of photoluminescence from the material being analyzed and the substrate on which it is supported. We then explain how to select an excitation wavelength that does not generate photoluminescence, reduces the noise level, and yields a Raman spectrum with a superior signal-to-noise ratio. |
