来源：ACS PublicationsThis study reports the synthesis of two rare-earth imidonitridophosphates and a series of 3d transition metal imidonitridophosphates (MIIIH3P6N12 with M = V, Cr, Eu, Lu, and MIIH4P6N12 with M = Mn, Fe, Co, Ni) by high-pressure metathesis. The crystal structures were elucidated by a combination of single-crystal and powder X-ray diffraction, elemental analysis, and vibrational spectroscopy. All compounds crystallize in the orthorhombic crystal system (transition metal imidonitridophosphates: Cmce, EuH3P6N12: Pna21, LuH3P6N12: Pbam) and feature a layered anionic network compos...

来源：ACS PublicationsEnergy consumption is one of the most important concerning issues of environmental problems especially the global warming phenomenon, with energy usage being the main cause. To reduce the energy used for cooling systems, development of material for smart buildings for near-infrared (NIR) protection is a challenge of material society. Metal oxides including tin oxide (SnO2) with an antimony (Sb) dopant are a candidate owing to their NIR shielding property. However, the upgrading of NIR absorption performance with rare-earth doping due to the specific property of rare-earth el...

来源：ACS PublicationsRare-earth (RE) doping has proven to be effective in enhancing the luminescent and optoelectronic properties of halide perovskites (HPs). However, the growth of RE-doped halide perovskite single crystals remains challenging. Herein, we successfully synthesized nine distinct MAPbBr3:RE (RE = Yb, Eu, Tb) single crystals (6–8 mm in size, RE/Pb = 0.008–0.053%) through systematic optimization of RE reagents, growth temperature, and solution concentration. Structural and optical characterization revealed RE-induced lattice expansion and band gap modulation, confirming the effectiv...

来源：ACS PublicationsTo meet the requirements for remote optical thermometry, Er3+- and Ho3+-doped Cs2NaYbCl6 double perovskites with intense upconversion (UC) emissions were designed. Excited by 980 nm, characteristic emissions of Er3+ and Ho3+ were detected, with optimal doping concentrations of 30 and 50 mol % in the Cs2NaYbCl6 host, respectively. The near-infrared light-triggered UC luminescence mechanism was investigated through the pump power-dependent UC emission spectra. Moreover, using the fluorescence intensity ratio (FIR) technique, temperature sensing performance was explored by anal...
