Effect of Dopants or Impurities on the Raman Spectrum of the Host Crystal
David Tuschel
Raman spectroscopy is a convenient method for probing the chemical bonding and solid state structure of crystals, and it is sensitive to the presence of dopants, impurities, and crystal defects in the host-crystal lattice. Here is what you need to know about how a host-crystal Raman spectrum is affected by dopants and impurities.
