In the version of the News & Views article 'X-ray imaging: Perovskites target X-ray detection' originally published (Nature Photon. 10, 288–289; 2016), in ref. 11, the second author's surname was misspelt and accents were missing from all surnames; the author list should have read 'Náfrádi, B., Náfrádi, G., Forró, L. & Horváth, E.'. Corrected in the online versions 11 May 2016.
