[Study on the inkblot of carbon pen fields by Raman micro-spectroscopy].
The four carbon-pen inkblots in market were studied by Raman micro-spectroscopy. The Raman spectra obtained in the experiments indicated that four brands of carbon-pen have not only similarity but also differentiation. Raman spectra from the same brand but different batch demonstrated difference too. Hence one can use the Raman technique for characterization and identification of inkblots from market.
