Synthesis, optical properties, and growth mechanism of blue-emitting CdSe nanorods

Thoma, Steven G.; Sanchez, Arturo; Provencio, P.N.; Abrams, B.L.; Wilcoxon, Jess P.

Blue-emitting, cubic phase CdSe nanorods with an approximate diameter of 2.5 nm and lengths up to 12 nm have been synthesized at low temperature (100 °C) in a single surfactant using a single-source molecular precursor. Transmission electron microscopy and dynamic light scattering measurements indicate that the nanorods are formed from self-assembly of isotropic nanoclusters. Anisotropic growth in a single surfactant appears to be favored when growth occurs below the thermal decomposition temperature of the single-source precursor. © 2005 American Chemical Society.
