Fundamental understanding of the effect doping on optical properties 3D double perovskites (DPs) especially dynamics self-trapped excitons (STEs) is vital importance for their optoelectronic applications. Herein, a unique strategy via Cu+ to achieve efficient STE emission in alloyed lead-free Cs2 (Ag/Na)InCl6 DPs reported. A small amount (1.0 mol%) results boosted crystals, with photoluminescence (PL) quantum yield increasing from 19.0% 62.6% and excitation band shifting 310 365 nm....
Currently, lanthanide (Ln3+ )-doped near-infrared (NIR)-emitting double perovskites (DPs) suffer from low photoluminescence quantum yield (PLQY). Herein, we develop a new class of NIR-emitting DPs based on Ln3+ -doped Cs2 (Na/Ag)BiCl6 . Benefiting the Na+ -induced breakdown local site symmetry in AgBiCl6 DPs, effective NIR emissions are realized through Bi3+ sensitization. Specifically, 7.3-fold and 362.9-fold enhanced Yb3+ Er3+ achieved Ag0.2 Na0.8 BiCl6 relative to those Na-free...

The synthesis of atomically thin transition-metal oxide nanosheets as a conceptually new class materials is significant for the development next-generation electronic and magnetic nanodevices but remains fundamental chemical physical challenge. Here, based on "template-assisted oriented growth" strategy, we successfully synthesized half-unit-cell typical α-Fe2O3 that show robust intrinsic ferromagnetism 0.6 μB/atom at 100 K remain ferromagnetic room temperature. A unique surface structure...
Lanthanide ion (Ln3+ )-doped halide double perovskites (DPs) have evoked tremendous interest due to their unique optical properties.

To facilitate phosphor-converted light-emitting diodes (LEDs) for plant growth, the development of phosphor materials with efficient red or far-red emission is essential.
Abstract Highly efficient near‐infrared (NIR) luminescent nanomaterials are urgently required for portable mini or micro phosphors‐converted light‐emitting diodes (pc‐LEDs). However, most existing NIR‐emitting phosphors generally restricted by their low photoluminescence (PL) quantum yield (QY) large particle size. Herein, a kind of highly NIR nanophosphors is developed based on copper indium selenide dots (CISe QDs). The PL peak these QDs can be exquisitely manipulated from 750 to 1150 nm...
