In situ high pressure-temperature Raman spectroscopy technique with laser-heated diamond anvil cells

We describe an in situ high pressure-temperature Raman technique for studying materials in laser-heated diamond anvil cells using a Nd:YLF laser s1053 nmd as the heating source and an ion laser as the Raman exciting source. Here we introduce the method of laser heating transparent samples using a metallic foil (Pt,Re, or W) as the laser absorber (internal heating furnace) in a diamond cell. The...

High-Temperature Raman Spectroscopy of Nano-Crystalline Carbon in Silicon Oxycarbide

The microstructure of segregated carbon in silicon oxycarbide (SiOC), hot-pressed at T = 1600 °C and p = 50 MPa, has been investigated by VIS Raman spectroscopy (λ = 514 nm) within the temperature range 25-1000 °C in air. The occurrence of the G, D' and D bands at 1590, 1620 and 1350 cm-1, together with a lateral crystal size La < 10 nm and an average distance between lattice defects LD ≈ 8 nm,...
