Naoki Noguchi, Ahmadjan Abduriyim, Ichiko Shimizu, Nanako Kamegata, Shoko Odake and Hiroyuki Kagi Imaging of internal stress around a mineral inclusion in a sapphire crystal: application of micro-Raman and photoluminescence spectroscopy Journal of Raman Spectroscopy 44
We developed a micro-Raman and photoluminescence imaging technique for visualize the internal stress fields in a sapphire crystals. The technique was applied to an Australian sapphire with a zircon inclusion. The Raman mapping data of sapphire around the zircon inclusion were converted to deviatoric components of stress tensor.
