On page 699, C.‐S. Lee, M.‐F. Lo, and co‐workers report a black‐colored MoO 3 obtained by vacuum annealing of typical transparent MoO 3 . The black color is caused by splitting of the original wide bandgap into two regions of 1.8 and 1.0 eV widths. This enables IR absorption and the fabrication of a black MoO 3 ‐based photodetector with response across the full UV–visible–IR spectral range.
