abstract = {Highly anisotropic single perovskite nanorods (NRs) offer polarized emission and high photoluminescence (PL) quantum yields, making them promising candidates for quantum light sources. Here, we make use of the quantum-confined Stark effect (QCSE) to tune the optical response of individual CsPbBr3 NRs with well-defined orientation relative to an external electric field. PL spectroscopy reveals a reversible QCSE, allowing to extract the polarizability and to prove the existence of a permanent dipole moment. A clear relation between field-induced emission energy shift, spectral line broadening, and PL intensity quenching is found. Interestingly, our study reveals a correlation between polarizability and zero-field PL intensity, hinting towards a screening effect of the passivating ligands. These findings offer a strategy for tuning perovskite NC emission, e.g., with respect to a cavity mode, in a well-defined way.}
