We report a correlation between the structural phase transition of CsPbX<sub>3</sub> (X=Cl, Br, I) nanocrystals (NCs) and their temperature dependent steady-state photoluminescence (PL) and time-resolved PL (TRPL). In constrast to CsPbBr<sub>3</sub> and CsPbI<sub>3</sub> NCs which exhibited a continuous blue shift in their bandgap with increasing temperature, the CsPbCl<sub>3</sub> exhibited a blue shift until ~193 K, followed by a red shift until room temperature. We attribute this change from ...[more]
