| Bismuthide are kinds of Semiconductor Nanocrystals meterials with outstanding functionality. They are widely used in optical and electrical devices. In order to obtain materials with particular compositions, sizes and shapes, it is essential to create simple, general and invironment friendly synthetic methods, and study the growth mechanism of nanocrystals. Assembling the nanocrystals into advanced functional structure system also paves the way for the practical applications. In this paper, two branch of the bismuthide has been done deeply research on their synthesis with organization. The size and morphology of the products characterized by X-Ray Diffractomer (XRD),Transmission electron microscopy (TEM) and scanning electron microscope(SEM).The optical properties was tested by Ultraviolet and visible absorption spectroscopy (UV-VIS) and photo luminescence (PL). We also use electrochemical workstation to measure their Li-ion battery performance.In the part of bismuthide/antimonide synthesis, a general route of synthesis nanocrystals by hot-injection in oil phase has been exploited. This method for bismuth sulfide can make accurate controllability on shape and size feasible. Photocatalytic degradation of rhodamine B has been investigated on the as-obtain nanocrystals. The results show that the degradation efficiency on rhodamine B has size-dependence.In the part of Bi/Sb-base bimetallic and other compounds synthesis, we also get a gerneral process to prepare. In them, the Li-ion battery properties of the nickelantimonide made through this way has largely enhanced. Due to the lower cost and Settable, this solvent system----polyethylene glycol 400(PEG400) by seed spreading is illuminated for bimetallic compounds development on Li-battery in the future. After this, combine with two parts of synthetic method above, Pd-Cd alloy ultrathin nanowires has been obtained successfully in octadecylamine system, adding some special post treatment.
