摘要

Abstract

Lead-free halide double perovskites (LFHDPs) have gained prominence as eco-friendly optoelectronic materials due to their structural stability and flexible tunability. Lanthanide (Ln

) ions have rich energy levels

hich can endow LFHDP materials with emissions ranging from visible to near-infrared (NIR) region through the ion doping strategy. However

their NIR applications remain limited by narrowband emission and low photoluminescence quantum yield (PLQY) due to weak absorption cross-section. Herein

NaInCl

: Ln

were successfully synthesized

and the problem of low absorption of Ln

ions is effectively solved. Incorporating Mo

/Ag

ions achieves a near-unity PLQY and expands the excitation spectrum across the full visible range and a small part of NIR region (250–850 nm). Mechanism analysis revealed synergistic energy transfer pathways involving self-trapping excitons and intermediate energy states of Mo

ion

enhancing both photon absorption and PLQY. The universal applicability of this approach has been validated across Bi-based and multiple lanthanide ions (Ln: Ho

Yb). These optimized materials demonstrate exceptional broadband emission characteristics suitable for multi-scenario NIR applications

including light-emitting-diodes (LEDs)

night vision

imaging

anti-counterfeiting technologies. This co-doping methodology establishes a versatile framework for overcoming inherent limitations in Ln

-activated materials

offering new possibilities for efficient NIR optoelectronic devices.
