Аннотация: <jats:title>Abstract</jats:title><jats:p>Zero-dimensional (0D) metal halides have drawn increasing attention due to the attractive structure dependent photoluminescence (PL) properties. Here, we report two new 0D organic–inorganic hybrid Sb-based halides, (MTP)<jats:sub>6</jats:sub>SbBr<jats:sub>6</jats:sub>Sb<jats:sub>2</jats:sub>Показать полностьюBr<jats:sub>9</jats:sub>⋅H<jats:sub>2</jats:sub>O (MTP=Methyltriphenylphosphonium, crystal 1) and (MTP)<jats:sub>2</jats:sub>SbBr<jats:sub>5</jats:sub> (crystal 2), featuring a reversible structural phase transformation and tunable orange and red emissions upon dehydration and rehydration of H<jats:sub>2</jats:sub>O molecules. Intriguingly, a subsequent heat treatment further enables the formation of glassy state (MTP)<jats:sub>2</jats:sub>SbBr<jats:sub>5</jats:sub> (glass 3) with near-infrared luminescence, moreover, a sequential reverse phase transformation from glass 3 to crystal 2 and 1 is triggered by acetonitrile and water vapor stepwise. The anti-counterfeiting demo based on the tunable and reversible PL switching is finally achieved and thus the phase structure engineering in 0D metal halides expands their multiple applications in optical fields.</jats:p>
