通过在己基膦酸和三辛基氧化膦的混合物中生长纳米粒子，形成了极高长径比的CdSe纳米棒(30：1)以及箭头形、泪滴形、四针形和支链四针形的CdSe纳米晶。对板形控制影响最大的因素是表面活性剂的配比、进样量和单体浓度随时间变化的情况。
The formation of extremely high aspect ratio CdSe nanorods (30:1) as well as arrow-, teardrop-, tetrapod-, and branched tetrapod-shaped nanocrystals of CdSe, has been achieved by growth of the nanoparticles in a mixture of hexylphosphonic acid and trioctylphosphine oxide. The most influential factors in shape control are the ratio of surfactants, injection volume, and time-dependent monomer concentration.
