I disagree with Emmanuel, UV Raman is an established technique, fluorescence
seems to be a problem above 300 nm, Semrock has some information on their
website. However you need special lasers, optics, spectrometer and detectors
which are more expensive and you might damage your sample easily. For
biological samples near IR is the wavelength of choice. 
In your sentence you would say "scattered" instead of "reflected" Raman
signal, it scatters can go in all directions.
