Uniform Luminous Perovskite Nanofibers with Color‐Tunability and Improved Stability Prepared by One‐Step Core/Shell Electrospinning

On page 4 of the original manuscript, the description of the band gap is erroneously given in reverse order.The correct sentence should read: "According to the onset of Kubelka-Munk-transformed diffuse reflectance spectrum (Figure 3a), the bandgaps of the MAPbCl 3 -1, MAPbBr 3 -1, and MAPbI 3 -1 fibers are estimated to be 3.04, 2.32, and 1.63 eV, respectively."The above error does not affect the scientific conclusions drawn from the work.The authors apologize for any inconvenience or misunderstanding that this error may have caused.
