英文摘要： Semiconductor-metal hybrid heterostructures are promising building blocks for applications in catalytic, biomedical, and optoelectronic devices. The proposal was aimed at the purposeful design and synthesis of Ⅱ-Ⅵ group one-dimensional semiconductor/magnetic metal nanoheterostructures in mild liquid system for understanding the key scientific problems of how reaction conditions and material combinations can be tuned to influence the growth mechanism of the hybrid material and the synergistic effect of the components. The semiconductor/magnetic metal nanoheterostructures with novel structure and specific composition will be prepared in liquid condition by selecting the proper precursor, solvent and complexing agent, etc. The research will be based on the binary nanoheterostructure, and further constructed the complex ternary or more multicomponent nanoheterostructure. It will be studied how to tune the reaction conditions to change the composition, structure and the combination of the components that further affect the growth mechanism, providing technical support for the preparation of complex nanoheterostructures with high properties. The photoluminescence and magnetic properties of the heterostructures will be researched as well as the relationship between the composition, structure and properties for understa
