Abstract Lead‐free halide double perovskites are rapidly gaining prominence as a nontoxic, highly stable, and versatile alternative to traditional lead‐based perovskites, notable for their superior optoelectronic properties. Among these, rare‐earth‐based (RHDPs) notably stand out. Comprising fifteen lanthanide elements with distinctive electron configurations of [Xe] 4f n−1 5d 0−1 6s 2 ( n = 1–15), alongside the group‐IIIB Yttrium (Y) Scandium (Sc), rare‐earth (RE) exhibit great potential. These 17 RE ions (Sc 3+ , Y La –Lu ) offer vast landscape crafting numerous RHDPs, poised properties that surpass diversify beyond current perovskite standards. Key functionality unique luminescence driven by self‐trapped exciton (STE) recombination, 4f→4f 5d→4f transitions, enabling applications in visible infrared light emission through downshifting up‐conversion. This review thoroughly articulates foundational including structural‐property relationships, synthesis methods, optical characteristics, durability. It highlights recent advancements across range fields such near‐infrared emitting diodes (Vis&NIR LEDs), sensors, anti‐counterfeiting technologies. Additionally, discusses prevailing challenges associated RHDP materials applications, offering insights future directions.
