At 300 K on polycrystalline Be the Raman line was observed at 455 cm.(line width Δω ≈ 16 cm.) with 4880 Ǻ (Ar ion laser) excitation as the Stokes line . At room temperature on single crystal Be with the polished surface in the crystallographic x-z plane, the line was obmechanism 发表于 2025-3-25 00:09:22
