Observation of crystal structure orientation by cathodoluminescence (CL) polarization-filtered spectrum imaging
Gatan instrument used
The Monarc® Pro system offers the most complete analysis of cathodoluminescence (CL) emissions and empowers all users to capture the highest quality data, whether novice or expert.
Background
The structures, compositions, and history of various geological specimens can be discovered using CL microscopy, where the spatial and/or spectral variation in the luminescence signal of a mineral-thin section reveals the distribution(s) of trace elements reconstruct the geological history. Despite polarization studies forming a key component of optical microscopy analysis of mineral-thin sections, the polarization state of the CL signal has been ignored (presumably) due to the unavailability of appropriate analysis tools.
