A novel visible-light-driven photochromic material with high-reversibility: tungsten oxide-based organic–inorganic hybrid microflowers†
Abstract
3D tungsten-oxide-based organic–inorganic microflowers with sizes of 1–5 μm have been prepared by an economical non-aqueous route in a large quantity, and they exhibit visible-light coloration, good reversibility and an enhanced photochromic response.
