Ionothermal synthesis of a photochromic inorganic–organic complex for colorimetric and portable UV index indication and UVB detection

Abstract

A photochromic inorganic–organic complex was ionothermally synthesized via a decomposition-reassembly strategy, which is highly promising for the colorimetric and portable indication of UV index and quantification of UVB doses.
