Data for "Estimation of semiconductor-like pigment concentrations in paint mixtures and their differentiation from paint layers using first-derivative reflectance spectra"
No full textThis repository contains key raw data to accompany the article "Estimation of semiconductor-like pigment concentrations in paint mixtures and their differentiation from paint layers using first-derivative reflectance spectra".
The repository includes a complete set of reflectance spectra recorded from the paint samples prepared for this work, plus the optimised structures and electronic density-of-states and band-dispersion curves obtained from complementary modelling studies on the three coloured pigments investigated, viz. alpha-HgS (vermillion), tetragonal Pb3O4 (red lead) and SnPb2O4 (lead-tin yellow).
Abstract of the publication:
Identification of the techniques employed by artists, e.g. mixing and layering of paints, if used together with information about their colour palette and style, can help to attribute works of art with more confidence. In this study, we show how the pigment composition in binary paint mixtures can be quantified using optical-reflectance spectroscopy, by analysis of the peak features corresponding to colour-transition edges in the first-derivative spectra. This technique is found to be more robust than a number of other spectral-analysis methods, which can suffer due to shifts in the transition edges in mixed paints compared to those observed in spectra of pure ones. Our method also provides a means of distinguishing paint mixtures from layering in some cases. The spectroscopy also shows the presence of multiple electronic transitions, accessible within a narrow energy range, to be a common feature of many coloured pigments, which electronic-structure calculations attribute to shallow band edges. We also demonstrate the successful application of the reflectance-analysis technique to painted areas on a selection of medieval illuminated manuscripts

Dataset for ORCID EPrints Implementation
Get PDFA survey canvassing user requirements for integration of EPrints software with the ORCID service was circulated to four mailing lists. Although the target audience was the UK EPrints user community, the survey was open to anyone, so included a number of international responses. This dataset includes an anonymised version of the download of results from Bristol Online Surveys and a copy of the survey form.A survey was circulated to four mailing lists - [email protected], [email protected], [email protected], [email protected]
