In article number 1901345, Min Gu and co‐workers show that the luminescence from upconversion nanoparticles can be modulated with high efficiency at a millisecond timescale by photochemically derived graphene. On the cover picture, the image of an optical pattern displays the representation of a kangaroo composed by individual pixels which are retrieved distinctly through upconversion luminescence quenching by photochemically derived graphene under near‐infrared irradiation.
