The synthesis of SbSI rodlike crystals with studded pyramids

摘要

The SbSI rodlide crystals with studded pyramids were synthesized from the reaction among antimony trichloride, thiourea, and excessive sodium iodide under moderate hydrothermal conditions at 200 deg C. The final products were characterized by XED, SEM, XPS, and elemental analysis. The SEM images showed the SbSI rodlike crystals are inserted some octahedrons on the surfaces of the rods. Typically, the structure is 3-4mm in length,8-10um in diameter for a singular crystal.
