封面介绍Wang, Qiushi et al. on page 196-207: This study reports the rapid synthesis of ZnO:Er3+/Yb3+ hierarchical nanorods through the direct current arc discharge plasma method. The material enables three-mode optical thermometry by integrating the fluorescence intensity ratio signals from both thermally coupled and non thermally coupled energy levels of Er3+ ions, along with the fluorescence lifetime signal of the 4S3/2 level. This three-mode optical thermometry overcomes single mode detection blind zones promising potential for advanced temperature sensing.

封面介绍Wu, Jihuai & Lan, Zhang et al. on page 223-230: In this study, 2-aminobenzothiazole (BTA) was introduced as a multifunctional molecular bridge. BTA forms an electric dipole layer at the interface, which facilitates efficient hole extraction and transport, thereby significantly enhancing the performance and stability of CsPbI2Br devices. This demonstrates that BTA interface modification is an effective strategy for improving photovoltaic performance and stability. In the future, screening molecules with stronger dipole moments could further optimize the interface performance, promoting the development of such low-cost, high-efficiency, and stable inorganic perovskite solar cells.
