Highly Efficient Manganese Bromides with Reversible Luminescence Switching through Amorphous-Crystalline Transition.

ABSTRACT: While luminescent stimuli-responsive materials (LSRMs) have become one of the most sought-after materials owing to their potential in optoelectronic applications, the use of earth-scarce lanthanides remains a crucial problem to be solved for further development. In this work, two manganese-based LSRMs, (R)-(+)-1-phenylethylammonium manganese bromide, (R-PEA)₂MnBr₄, and (S)-(-)-1-phenylethylammonium manganese bromide, (S-PEA)₂MnBr₄, are successfully demonstrated. Both (R-PEA)₂MnBr₄ and (S-PEA)₂MnBr₄ show a kinetically stable red-emissive amorphous state and a thermodynamically stable green-emissive crystalline state at room temperature, where the fully reversible transition can be done thro
