SUMMARY

Raman spectra were acquired using a Horiba JobinYvon Labram HR800 Raman microscope with 532 nm continuous-wave laser excitation (diode-pumped solid-state laser, 40 mW maximum power at the sample surface, reduced to 20 mW by a neutral density filter). Single spectra, acquired independently of mappings, were typically measured within 1 min split into several accumulations . . .
