Quantum-sized CdS nanorods were synthesized by direct thermal decomposition of a single-source precursor in a monosurfactant system. The CdS nanorods were uniform, had high crystallinity, and exhibited strong quantum confinement effect. The nanorod growth was controlled by an oriented attachment mechanism, and the morphology was determined by the competition between dipole attraction and steric repulsion of nanodots. Increasing precursor concentration and prolonging reaction time were favorable for the formation of CdS nanorods.
量子尺寸的 CdS 纳米棒通过在单一组分表面活性剂体系中单源前体制备物的直接热分解来合成。CdS 纳米棒具有均匀性、高结晶度和强量子限制效应。纳米棒的生长受定向附着机制控制，形态由纳米点的偶极力和空间排斥力之间的竞争决定。增加前驱体浓度和延长反应时间有利于 CdS 纳米棒的形成。
