Halide perovskite quantum dots (PeQDs) are characterized by a size-dependent emission spectrum and an intrinsic lack of preferential emission directions. Thus, new means for shaping the typical Lambertian angular profile of thin layers embedding such PeQDs are highly desirable for several photonics applications, including solid-state lighting devices. Here, we show that the photoluminescence pattern of PeQDs can be changed drastically by weakly coupling them to plasmonic lattices at emission wavelengths. The coupling to extended collective optical modes supported by the lattices converts the ensemble of incoherent randomly oriented emitters into a spatially coherent source of polarized light with a wavelength-dependent intensity enhancement of about one order of magnitude. The dispersive character of the narrow collective optical modes is key to achieving intensity enhancement of the entire perovskite emission spectrum, especially its tails, together with beaming into definite directions. Further, we optimize the thickness of the perovskite layer to realize simultaneous shaping of its emission by plasmonic lattices of different symmetries. This flexibility paves the way to designing advanced photonic architectures based on PeQDs for solid-state lighting applications requiring programmable emission patterns.
