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.

Abstract Room temperature phosphorescence (RTP) materials are of significant attentions due to their unique optical properties and potential applications in anti‐counterfeiting information security. However, single spatial resolution decryption methods fail meet high‐level security demands. A novel dual‐mode encryption strategy based on self‐trapped exciton (STE) fluorescence is proposed. By introducing ns 2 metal ions into the zero‐dimensional organic–inorganic hybrid halide (Ph 3 S) SnCl 6 , energy transfer pathways from S 1 T n levels STEs constructed, enabling precise control performance. This material exhibited STE fluorescence‐phosphorescence with different afterglow time, which can be utilized develop high‐performance time‐resolved cryptographic systems. Femtosecond transient absorption experiments indicated that rate significantly affected characteristics long materials. The this systems demonstrated, enhancing through multi‐level providing a new avenue for advanced
