| description | Abstract The interaction of light with solids can be dramatically enhanced owing to electron‐photon momentum matching. This mechanism manifests when light scattering from nanometer‐sized clusters including a specific case of self‐assembled nanostructures that form a long‐range translational order but local disorder (crystal‐liquid duality). In this paper, a new strategy based on both cases for the light‐matter‐interaction enhancement in a direct bandgap semiconductor – lead halide perovskite CsPbBr3 – by using electric pulse‐driven structural disorder, is addressed. The disordered state allows the generation of confined photons, and the formation of an electronic continuum of static/dynamic defect states across the forbidden gap (Urbach bridge). Both mechanisms underlie photon‐momentum‐enabled electronic Raman scattering (ERS) and single‐photon anti‐Stokes photoluminescence (PL) under sub‐band pump. PL/ERS blinking is discussed to be associated with thermal fluctuations of cross‐linked [PbBr6]4‐ octahedra. Time‐delayed synchronization of PL/ERS blinking causes enhanced spontaneous emission at room temperature. These findings indicate the role of photon momentum in enhanced light‐matter interactions in disordered and nanostructured solids. |
