Abstract Lanthanide‐based NIR‐II‐emitting materials (1000–1700 nm) show promise for optoelectronic devices, phototherapy, and bioimaging. However, one major bottleneck to prevent their widespread use lies in low quantum efficiencies, which are significantly constrained by various quenching effects. Here, a highly oriented (222) facet is achieved via engineering Cs 2 NaErCl 6 double perovskites, enabling near‐complete suppression of NIR‐II luminescence quenching. The optimally (222)‐oriented Ag 0.10 Na 0.90 ErCl microcrystals emit Er 3+ 1540 nm light with unprecedented high efficiencies 90 ± 6% under 379 UV excitation (ultralarge Stokes shift >1000 nm), record near‐unity yield 98.6% also obtained (222)‐based NaYb 0.40 0.60 Cl microcrystallites 980 excitation.

Abstract Nanomaterial‐based luminescence thermometry enables non‐invasive in vivo temperature measurement with high spatial resolution, which is crucial for driving advancement diagnostic and therapeutic technologies. However, spectral distortions signal attenuation resulting from complex light‐tissue interactions pose substantial challenges to the practical application of this method.
