Triple-grating Vis/UV Raman micro-spectrometer

拉曼光谱仪将用于研究相变过程中的原子重排，晶体和无序合成材料和矿物中的精细结构，以及亚微米尺度的非均匀材料的结构变化。拉曼信号与特定原子基团的对称性和成键直接相关。我们将把拉曼光谱应用于钙钛矿型和焦绿石型铁弹性和铁电复合氧化物、牙科羟基磷灰石、生物相容磷灰石基复合材料、变质矿物等。所获得的结果将对定制新的合成材料和矿物的功能化具有重要的基础性和技术意义。

The Raman spectrometer will be used for studying the atomic rearrangements during phase transitions, the fine-scale structure in crystalline and disordered synthetic materials and minerals, and for mapping the structural alteration in submicron-scale inhomogeneous materials. The Raman signalsare directly related to the symmetry and bonding of definite atomic groups. We will apply Raman spectroscopy to ferroelastic and ferroelectric complex oxides of perovskite- and pyrochlore-type, dental hydroxyapatite, biocompatible apatite-based composites, metamict minerals etc. The obtained results will be of fundamental importance as well as of technological significance for tailoring new synthetic materials and for the functionalisation of minerals.
