Fig. 2 The Raman spectra measured in the mixture of standard air and (a) 0.5% CO2, (b) 0.1% SF6, (c) 0.5% CO2 and 0.1% SF6; (d) The Raman spectrum captured in the mixture of standard air ...

（a）Synthetic schematic diagram of Bi/Bi2O3. (b) Time-dependent Raman spectra at −1.01 V vs. RHE. (c) Potential-dependent Raman spectra in the CO2-saturated electrolyte. (d) Linear sweep ...

Optimized optical components enable Raman spectra to be recorded at each image pixel with acquisition times on the order of milliseconds. Due to its confocal beampath, it is not only possible to ...
