Raman microspectroscopy of some iron oxides and oxyhydroxides

TL;DR: In this paper, the laser power dependence of the spectra of oxides and oxyhydroxides was investigated by using Raman microscopy, and it was shown that increasing laser power causes the characteristic bands of hematite to show up in the spectrum of most of the compounds studied.
Journal ArticleDOI

Heated goethite and natural hematite: Can Raman spectroscopy be used to differentiate them?

TL;DR: In this article, the authors used XRD, TEM and TG as supporting techniques to obtain both ex situ and in situ Raman spectra for disordered hematite.
Journal ArticleDOI

Characterization of corrosion products formed on steels in the first months of atmospheric exposure

TL;DR: In this article, the corrosion products of carbon steel and weathering steel exposed to three different types of atmospheres, at times ranging from one to three months, have been identified.
Journal ArticleDOI

Influence of the N-[methylpyridyl]acetamide ligands on the photoluminescent properties of Eu(III)-perchlorate complexes

TL;DR: In this paper, the synthesis, characterization and spectroscopic studies of Eu(III)-perchlorate complexes with amide ligands derived from N -[ x -methylpyridyl]acetamide where x = 3, 4 and 6.
Journal ArticleDOI

Raman Spectroscopic Analysis of Ancient Egyptian Pigments

TL;DR: The application of FT-Raman spectroscopy and visible Raman microscopy to the nondestructive analysis of pigment specimens excavated from Tell el Amarna by Flinders Petrie in the 1890s has provided information about the chemical composition of the materials used by XVIIIth Dynasty artists in the New Kingdom at the time of King Akhenaten, c. 1340 BC as discussed by the authors.
