Abstract Halide perovskites (HPs), emerging as a noteworthy class of semiconductors, hold great promise for an array optoelectronic applications, including anti‐counterfeiting, light‐emitting diodes (LEDs), solar cells (SCs), and photodetectors, primarily due to their large absorption cross section, high fluorescence efficiency, tunable emission spectrum within the visible region, tolerance lattice defects, well adaptability solution‐based fabrication processes. Unlike luminescent HPs with band‐edge emission, trivalent rare‐earth (RE) ions typically emit low‐energy light through intra‐4f optical transitions, characterized by narrow spectra long lifetimes. When fused, cooperative interactions between REs endow resulting binary composites not only properties inherited from parent materials but also introduce new attributes unattainable either component alone. This review begins fundamental characteristics REs, followed particular focus on impact electronic structures associated energy transfer The advanced synthesis methods utilized prepare HPs, RE‐doped compounds, are overviewed. Furthermore, potential applications summarized across diverse domains, high‐fidelity anticounterfeiting, bioimaging, LEDs, photovoltaics, photodetection, photocatalysis, conclude remaining challenges future research prospects.
