Tunable Multicolor Luminescence in Double Perovskite [(CH)N]KEuTb(NO) Single Crystals.

Tunable multicolor luminescence materials can flexibly meet the needs of smart lighting, enabling efficient light energy use and minimizing waste. Lead-free hybrid double perovskites AMM(NO) hold great potential in luminescence, benefiting from their tunable composition, high light absorption, low synthesis cost, and environmental friendliness. However, achieving tunable multicolor emission within a single matrix of these materials has yet to be realized.

Optimization of Sintering Conditions to Enhance the Dielectric Performance of Gd and Ho Codoped BaTiO Ceramics.

BaTiO dielectric capacitors, one of the important energy storage devices, play critical roles in storing electricity from renewable energies of water, wind, solar, etc. The synthesis of BaTiO ceramics with weak temperature dependence and a high dielectric constant at room temperature (') is an urgent problem to meet the miniaturization and large capacity of dielectric capacitors. Doping rare earth elements into BaTiO can solve this problem, but it is still challenging.
