Farmers' perceptions of climate risk reflect their subjective probability weighting bias, which are the prerequisite for their adaptation decisions and thus shape their actions. As an adaptation strategy, farmers prioritized the technological measures of chemical input as the most simple and...

All inorganic lead halide cesium perovskite quantum dots(QDs) has attracted much attention due to its excellent luminescence properties, but further development is restricted by its stability and the existence of toxic element lead. In this paper, F/Mn- doped CsPb(Br/Cl) 3 QDs glass was prepared...
