| Zusammenfassung | The Raman band of the stretching vibration of interstitial oxygen molecules in glassy SiO2 is found at 1548.5±1 cm−1. By comparison with the Raman spectrum of gaseous O2 (Q band at 1555.5 cm−1), the concentration of the interstitial O2 molecules in Suprasil W1 synthetic fused silica is estimated as (8±3.5)×1017 (molecules O2)/cm³. This value is further used to calibrate the intensity of the Nd-YAG laser-excited O2 a→X infrared photoluminescence band at 1272.2 nm against the intensity of the fundamental Raman bands of glassySiO2. In this way, quantitative measurements of O2 concentrations in SiO2 down to at least ≈ 1016 molecules/cm³ are possible. |
