Abstract

Previous work has shown the potential of the Stokes/anti-Stokes intensity ratio from Raman spectroscopy for optically probing the temperature of materials. This paper uses the statistics of photon counting to set theoretical limits on the temperature accuracy of the technique, as well as developing an expression whereby the theoretical temperature uncertainty for any Raman band at a given temperature can be predicted. Comparison of the theory to experimental data is shown, and experimental limitations are discussed.
