[High temperature Raman spectroscopy techniques and its applications].

Based on the frequency and time domain characters of heat radiation, high temperature Raman spectroscopy techniques were aralyzed and summarized. Thereby, two high temperature Raman systems were set up. One is an accumulated time-resolved macro-Raman spectroscopy system, and the other is an accumulated time-resolved and confocal coupled micro-Raman spectroscopy system. Finally, their applications in the study of high temperature processes such as melt structure and phase transformation, crystallization as well as samples with high fluorescence were intrtoduced.
