Abstract
Optical absorption spectroscopy is an important materials characterization for applications such as solar energy generation. This data descriptor describes the to date (Dec 2018) largest publicly available curated materials science dataset for near infrared to near UV (UV-Vis) light absorbance, composition and processing properties of metal oxides. By supplying the complete synthesis and processing history of each of the 179072 samples from 99965 unique compositions we believe the dataset will enable the community to develop predictive models for materials, such as prediction of optical properties based on composition and processing, and ultimately serve as a benchmark dataset for continued integration of machine learning in materials science. The dataset is also a resource for identifying materials composition and synthesis to attain specific optical properties.

This study is based upon work performed by the Joint Center for Artificial Photosynthesis, a DOE Energy Innovation Hub, supported through the Office of Science of the U.S. Department of Energy (Award No. DE-SC0004993). We thank Kevin Kan for processing materials libraries. Author Contributions: H.S.S. and J.M.G. conceived the project and wrote the majority of code and manuscript. E.S. maintained the database backend and generated composition information. P.F.N. synthesized libraries and collected spectra. D.G. curated processing information and helped in generating the h5 container. J.M.G. supervised the research project. Code Availability: Custom code for handling the dataset is available at https://github.com/helgestein/materials-images-spectra/. This python code enables users to easily download the dataset, pull specific or random images and accompanying spectra as well as processing and composition data. The code is intended to enable easy exploration of the dataset and to provide templates for use in machine learning models. The code requires python version 3.6.4 or higher with the following packages: h5py > = 2.7.1, numpy > = 1.15.2, tqdm > = 4.23.0. The authors declare no competing interests. | ||||||||||||
