Simple drop‐deposition of ultrathin Bi 2 S 3 nanosheets allows the low‐cost construction of excellent flexible photodetectors. On page 2848, Q. Yang and co‐workers report a simple organometallic route to ultrathin Bi 2 S 3 nanosheets with thicknesses down to 2.2 nm. The nanosheets can be applied for the fabrication of photoconductors that show high sensitivity to visible–NIR light from 405 to 780 nm with a high external photoresponsivity up to 4.4 A W −1 , a high detectivity of 1011 Jones, a response time as fast as 10 μs, and high flexibility and durability.
