Fig. 3: Characterizations of (BTPP)1.8(HTPP)0.2MnBr4 transparent scintillation screen and crystalline transformation.
a Temperature-dependent PL spectra from 30 °C to 150 °C, then quenching to 30 °C, indicating that as the temperature increases, the material state changes, leading to changes in the fluorescence performance (The snowflake represents quenching to RT). b The DSC of the (BTPP)1.8(HTPP)0.2MnBr4 transparent medium crystallizes at around 110 °C, then melts at 150 °C (Red) and is quenched to RT (Blue). c Formation of transparent glassy state: temperature-dependent XRD from RT to 150 °C, then quenching to RT. d Formation of polycrystalline state: temperature-dependent XRD from RT to 110 °C, then slowly annealing to RT. The diffraction peak of the crystal state remains unchanged after annealing at 110 °C (Tc) to RT. e Pictures of (BTPP)1.8(HTPP)0.2MnBr4 transparent medium under OM and POM that heating up from RT to 150 °C and then quenching to RT, indicating that crystallization begins at 110 °C and disappears in the field of view at 150 °C. Scale bars: 200 μm.
