Advances in Time-resolved Raman Spectroscopy for in Situ Characterization of Minerals and Organics

چکیده
Introduction: We present recent developments in instrumentation for in situ planetary time-resolved Raman spectroscopy, leading to improved performance and identification of both minerals and organics. The Time-Resolved Raman Instrument shown in Figure 1 builds on the widely used 532 nm (green) laser Raman technique, but uses time resolution to detect Raman spectral signatures while eliminating pervasive background interference caused by fluorescence from minerals and organics. The same technique enables operation in daylight conditions without the need for light shielding.

Miniaturized time-resolved Raman spectrometer for planetary science based on a fast single photon avalanche diode detector array.
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...
متن کاملTime-resolved Raman spectroscopy for in situ planetary mineralogy.
Planetary mineralogy can be revealed through a variety of remote sensing and in situ investigations that precede any plans for eventual sample return. We briefly review those techniques and focus on the capabilities for on-surface in situ examination of Mars, Venus, the Moon, asteroids, and other bodies. Over the past decade, Raman spectroscopy has continued to develop as a prime candidate for ...
متن کاملMineralogy, Raman spectroscopy and lattice parameter characterization of biotite with hexagonal structure from Borujerd hornfels and migmatites
Biotite is a common rock-forming mineral and accepts a variety of elements in its structure. The valuable information of crystallization conditions of the biotite mineral obtain on natural biotite composition. The biotite mineral is one of the main mineral phases of pelitic rocks which are formed in a wide range of geological conditions. In this research, microscopic mineralogy, Raman spectrosc...
متن کاملIn-situ synthesis and characterization of reduced graphene oxide –Ag nanocomposites
Reduced graphene oxide(rGO)–silver(Ag) nanocomposites have been prepared by using solution based facile one-pot synthesis process. The reaction process involves high-temperature liquid-phase exfoliation of graphite oxide and silver acetate in presence of N-N’dimethylformamide (DMF) solvent, resulting in simultaneous formation of rGO as well as Ag nanoparticles. Different nanocomposites have bee...
