Abstract
A calibration material for calibrating a Raman spectrometer includes: a reference material configured to emit a broadband spectrum of luminescence light in response to receiving excitation light; and an additional material exhibiting a distinct Raman band within a spectral measurement range of the Raman spectrometer. A method of calibrating at least one Raman spectrometer using the disclosed calibration material includes: determining emission spectra of the calibration material at multiple temperatures; and calibrating each Raman spectrometer based on a calibration spectrum of the calibration material determined by the Raman spectrometer; determining a temperature of the calibration material by Raman thermometry; and adjusting a determination of spectral intensity values of intensity spectra performed by the respective Raman spectrometer based on the calibration spectrum, the temperature of the calibration material during calibration, and the emission spectra of the calibration material.
