| description | In order to seek for new Raman crystals, the manuscript presented the discussion on the Raman frequency of α-quartz, β-quartz, as well as Pb<sup>4+</sup>-doped SiO<sub>2</sub> crystals at different temperature and pressure. The results demonstrated that as the pressure increased, the Raman lines shifted towards higher frequency for α-SiO<sub>2</sub> crystal, while for β-SiO<sub>2</sub> crystals, the main lines moved to lower frequency. Several new peaks were generated from the Pb<sup>4+</sup>-doped α-SiO<sub>2</sub> crystals. The Pb<sup>4+</sup>-doped β-SiO<sub>2</sub> crystals presented strong and ample Raman beams in the low-frequency range. The airfoil-shaped spectra appeared and broadened at high temperature and pressure. It could be inferred that the Pb<sup>4+</sup>-doped SiO<sub>2</sub> crystals were excellent Raman crystal candidates. |
