a Crystal structure of Nb18W16O93, viewing along c-axis. b XRD patterns of Nb18W16O93 in bleached and colored states. c CV curve of Nb18W16O93 at a scan rate of 100 mV s−1 vs Ag/AgCl between −1.6 and 0.4 V and d the two-dimensional contour plot of in-situ transmittance spectrum change with potential. The distribution of CIE and CIELAB color coordinates for the color of film under different bias is provided in Fig. S15 and Table S7. e XPS spectra of Nb 3 d, W 4 f of Nb18W16O93 in bleached/colored states and the K 2p of Nb18W16O93 in colored state.
