This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights  UV photo luminescence detection of PAHs is possible within synthetic and natural gypsum, and synthetic halite.  The most transparent minerals are more conducive to UV photoluminescence detection of trapped organic matter.  Iron oxide hampers but does not completely quench the UV photoluminescence emission.  The maturity of organic carbonaceous material influences the luminescence response, resulting in a reduced signal for UV excitation wavelengths down from 375 nm to 225 nm.

“…This advantage is compounded by the fact that in the deep UV (< ∼ 250 nm) the Raman is spectrally well separated from fluorescence, which may occur in these molecules. Longer wavelength UV (e.g., 355 nm) has also been demonstrated [22]. UV Raman (combined with time gating) has been applied to mineralogy using 248, 266, and 355 nm sources, with potential advantages demonstrated for Raman spectroscopy of calcite samples containing multiple luminescence centers [23].…”

We present recent developments in time-resolved Raman spectroscopy instrumentation and measurement techniques for in situ planetary surface exploration, leading to improved performance and identification of minerals and organics. The time-resolved Raman spectrometer uses a 532 nm pulsed microchip laser source synchronized with a single photon avalanche diode array to achieve sub-nanosecond time resolution. This instrument can detect Raman spectral signatures from a wide variety of minerals and organics relevant to planetary science while eliminating pervasive background interference caused by fluorescence. We present an overview of the instrument design and operation and demonstrate high signal-to-noise ratio Raman spectra for several relevant samples of sulfates, clays, and polycyclic aromatic hydrocarbons. Finally, we present an instrument design suitable for operation on a rover or lander and discuss future directions that promise great advancement in capability.

“…Raman scattering spectroscopy is well known for probing the physical and chemical properties of materials as well as the environmental effects that change these properties. It appears today as one of the efficient tools in numerous applications such as nuclear field, refractories mineralogy, in pigment analysis, and in planetary exploration owing to numerous instrumental developments (optics, fibers, and detectors). Despite these developments, some difficulties nevertheless remain, as for instance separating some various contributions from the Raman spectrum, such as luminescence, or thermal emission for high temperature measurements.…”

Raman spectroscopy is experimentally widely available and relatively simple to perform at room temperature. Some difficulties nevertheless remain, as for instance separating some various contributions from the Raman spectrum, such as thermal emission for high temperature measurements or luminescence. Here, an optimized time‐resolved Raman spectroscopy system based on a gated detection and a nanosecond pulsed laser excitation (30 ns width, 532 nm wavelength) is described. The system allows contactless Raman measurements, at high temperatures, of some materials such as zirconia and yttria. An example of Raman spectra collected on yttria at very high temperature up to 2100 °C is provided. This optimized system may also be used to discriminate between Raman scattering and luminescence as demonstrated in zirconia material.
