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

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, (
