Abstract
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 Pb4+-doped SiO2 crystals at different temperature and pressure. The results demonstrated that as the pressure increased, the Raman lines shifted towards higher frequency for α-SiO2 crystal, while for β-SiO2 crystals, the main lines moved to lower frequency. Several new peaks were generated from the Pb4+-doped α-SiO2 crystals. The Pb4+-doped β-SiO2 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 Pb4+-doped SiO2 crystals were excellent Raman crystal candidates.
