摘要
以自制的NaHSe乙醇溶液为硒源,在PEG-400无水体系中采用多元醇法,在180℃生长10h制备了直径100-200nm,长度可达十几微米的纳米线.产物通过XRD、TEM、HRTEM、FESEM、EDS和UV-Vis等手段进行了表征,并研究了不同多元醇对产物形貌的影响.研究表明,PEG-400作为结构导向剂在制备一维Sb2Se3纳米线中发挥着至关重要的作用,并且无水环境为纳米晶的生长提供了更加纯净的条件,有利于制备高质量的纳米晶.
Sb2Se3 nanowires （[001] orientation） with a diameter of 100-200 nm and high aspect ratio were successfully synthesized at 180℃ for 10h by a facile non-aqueous polyol method, where home-prepared NaHSe alcohol solution was used as selenium source and PEG-400 served as an excellent solvent and structure director. The product was characterized by XRD, TEM, SAED, HRTEM, EDS and UV-Vis spectroscope, respectively. The effect of different polyols on the final product＇s morphologes was investigated. The results indicated that the PEG-400 played the key role in the crystal anisotropic growth and the non-aqueous polyol system provided a clean crystal growth condition.
