Synthesis and Formation Mechanism of CdS Nanorods via Hydrothermal Microemulsion

Abstract

Abstract: Hexagonal cadmium sulfide nanorods with diameters of 30～80 nm and lengths up to 170～1110 nm were prepared in CTAB/water/hexane/n-pentanol quaternary
microemulsion under hydrothermal conditions at 130℃. The products were characterized by XRD, TEM, HRTEM, and EDS. The mediate tower-shaped
rods, being composed of triangular crystals coordinated along c-axis, were observed. While aging, sharp edges of the tower-shaped rods were greatly
blurred with the final product of smooth rods. Based on the facts, a direction aggregation process from triangular crystals to the final smooth
rods with the continuous provision of sulfide was proposed for the growth mechanism of nanorods.

Key words: microemulsion, hydrothermal, CdS, nanorods
