            Lead halide perovskites are intensively studied in past few years due to their
            potential applications in optoelectronic devices such as solar cells, photodetectors,
            light-emitting diodes (LED), and lasers. In addition to the rapid
            developments in material synthesis and device fabrication, it is also very
            interesting to postsynthetically control the optical properties with external
            irradiations. Here, the influences of very low energy (10–20 keV) electron
            beam of standard electron beam lithography are experimentally explored on
            the properties of lead halide perovskites. It is confirmed that the radiolysis
            process also happens and it can selectively change the photoluminescence,
            enabling the direct formation of nanolaser array, microsized light emitter
            array, and micropictures with an electron beam writer. Interestingly, it is
            found that discontinuous metallic lead layers are formed on the top and
            bottom surfaces of perovskite microplate during the radiolysis process, which
            can act as carrier conducting layers and significantly increase the photocurrent
            of perovskite photodetector by a factor of 217%. By using the electron
            beam with low energy to modify the perovskite, this method promises to
            shape the emission patterns for micro-LED with well-preserved optical properties
            and improves the photocurrent of photodetector.
