An optimized time‐resolved Raman spectroscopy system based on gated detection and a nanosecond pulsed laser excitation is described here. The system allows characterizing materials at high temperature by discriminating between Raman scattering and thermal emission. The optimized parameters were used to record in situ Raman data of polycrystalline c‐Y2O3 at high temperatures up to 2100 °C. In addition...
SrAl2O4 materials were obtained by molten salt synthesis and sintered at high temperatures to produce a ceramic body suitable for polarization‐resolved Raman spectroscopy measurements. Optimized experimental conditions were employed to study the complex vibrational spectrum of these ceramics under polarized light. A reliable set of experimental bands was obtained: 69 Raman modes were in fact observed,...
