英文摘要	At a low temperature of 550 degrees C, multiarmed US nanostructures were successfully prepared by thermal evaporation of US powders without use of any catalysts. The length and tip diameter of the arms in US multipods could be controlled by simply varying the growth time. With the arm length increasing, the tip diameter successively decreases. Short-armed multipods (SMPs) are made of both zinc blende and wurtzite phase US, while medium-armed multipods (MMPs) and long-armed multipods (LMPs) consist of only hexagonal phase CdS. LMPs exhibit good field-emission (FE) properties with relatively high field-enhancement factor and enhanced luminescence compared to SMPs and MMPs because of the needle-shaped arms and high crystallinity. Besides bind energy emission of US, LMPs exhibit it broad red emission in CL spectrum because of the arms with high aspect ratios.
