Acceleration of radiative recombination in quasi-2D perovskite films on hyperbolic metamaterials
Abstract
Hyperbolic metamaterials are a family of nanophotonic architectures allowing for the unique control of photonic local density of states. Such a property makes metamaterials prospective to use them with light-emitting objects or to apply as meta-electrodes for optoelectronic devices, where the control of recombination properties plays a decisive role. On the other hand, layered quasi-2D halide perovskites (Ruddlesden-Popper phase) attract high attention due to their low cost, broadband spectral tunability, and outstanding optoelectronic properties. Here, we show how to accelerate photoluminescence with smart engineering of photonic density of states (i.e., via the Purcell effect) by depositing a perovskite film on a hyperbolic metamaterial. We experimentally confirm acceleration of radiative recombination by almost 3 times. This effect can be useful in light-emitting devices, where interplay between radiative and non-radiative channels of charge carrier recombination is crucial.
