Resonance Raman (RR) peaks of CO and OH stretching modes and their higher harmonics have been observed superimposed on the photoluminescence (PL) spectrum of SnO2 thin films. Commercial fluorine doped SnO2 thin films deposited by sputtering on glass and SnO2 thin films deposited on Si by laser ablation have been studied. The dispersions of CO and OH stretching RR modes are ~600 cm−1 eV−1 and 800 cm−1 eV−1, respectively. The dispersion of the third harmonic of the CO stretching mode is ~2000 cm…
