N2 - Resonant diffractive optical elements can be used to create the desired spatialand angular distribution of scattered light in a narrow wavelength range.Exciton resonance could help to make such elements active. Here an excitondiffraction grating made from fully inorganic CsPbBr3 halide perovskite isdemonstrated. Spatial modulation of excitonic properties of the single crystalis achieved using local defect formation by 30 keV Ga+ focused ion irradiationwith low irradiation dose 1014 cm−2. Such a low dose prevents the appearanceof non-resonant diffraction since no sample milling occurs. The observeddiffraction reflex has a maximum efficiency of 2.3 × 10−3 at the free excitonresonance and 1.7 meV spectral width. The temperature, angular, and spectralproperties of resonant diffraction are studied. The possibility of creatingexciton diffraction gratings based on halide perovskites is one more confirmationof their applicability as a new material for information photonics.
