Reversible Structural Phase Transitions in Zero‐dimensional Cu(I)‐Based Metal Halides for Dynamically Tunable Emissions

Exploring structural phase transitions and luminescence mechanisms in zero-dimensional (0D) metal halides poses significant challenges, that are crucial for unlocking the full potential of tunable optical properties and diversifying their functional capabilities. Herein, we have designed two inter-transformable 0D Cu(I)-based metal halides, namely (C
