“…In contrast, LaOI nanocrystals exhibit an amorphous background only after 3 days indicating the appearance of LaI 3 (orange asterisks) domains with prolonged exposure (Figure S1B). These results are further concordant with moisture uptake studies performed by Eagleman et al., which revealed that oxyhalides show considerably lower moisture uptake as compared to their halide counterparts [27] …”

Ac hallenge in anion control in periodic solids is to preserve the crystal lattice while substituting for different anions of widely varying sizea nd hardness.P ost-synthetic modification routes that place cations or anions in nonequilibrium configurations are promising;h owever,s uch methods remain relatively unexplored for anion placement. Here,w er eport the synthesis of LaOI nanocrystals by an onhydrolytic sol-gel condensation reaction and their transformation into LaOBr,LaOCl, and LaOF nanocrystals along hardsoft acid-base principles using post-synthetic metathesis reactions with ammonium halides.A nion displacement proceeds along halide planes,p reserving the tetragonal matlockite structure.E nergy-variant X-raye xcited optical luminesce signatures of alloyed Tb 3+ -ions is asensitive quantum reporter of the preservation of the cation sublattice and hardening of the crystal structure upon anion replacement.

Highly Br ¹ ion conducting solid electrolytes were developed by replacing La 3+ ion site in LaOBr with lower valent Sr 2+ and Ca 2+ ions to form Br ¹ ion vacancies for Br ¹ ion conduction with suppressing the sample decomposition. By doping two kinds of divalent cations simultaneously into LaOBr lattice, high amount of Br ¹ ion vacancy was successfully introduced compared to the previously reported La 0.9 Sr 0.1 OBr 0.9. Among the samples prepared, the highest Br ¹ ion conductivity was obtained for the La 0.85 Sr 0.10 Ca 0.05 OBr 0.85 solid, which was ca. 5 times higher than that of La 0.9 Sr 0.1 OBr 0.9 .
