Screening combinatorial arrays of inorganic materials with spectroscopy or microscopy

A method for evaluating an array of materials, the method comprising

• providing an array of materials comprising at least ten different inorganic materials at discrete regions of a substrate, the array consisting essentially of the substrate and the materials, the regions being isolated such that the materials or components thereof cannot interdiffuse between adjacent regions after being formed or deposited on the substrate;
• and
• screening the array of materials using infrared spectroscopy.

A method for evaluating an array of materials, the method comprising

• providing an array of materials comprising at least ten different inorganic materials at discrete regions of a substrate, each of the at least ten materials comprising first and second components, with a gradient of stoichiometries as compared between the at least ten material-containing regions of the substrate, the regions being isolated, such that the materials or components thereof cannot interdiffuse between adjacent regions after being formed or deposited on the substrate;
• and
• screening the array of materials for a useful property of interest by using spectroscopy or microscopy to generate data, and analyzing the generated data to evaluate the materials, wherein the materials are screened using Raman spectroscopy.
