Thermally induced reversible phase transition and photoluminescence switching behavior of (NH4)2MnBr4(H2O)2 crystals

In this work, a novel and highly stable (NH 4 ) 2 MnBr 4 (H 2 O) 2 single crystal was synthesized, exhibiting PL switching behavior through a thermally induced reversible phase transition, and applied in anti-counterfeiting.
