“…35,36 In the bulk, both 1:1 and 2:1 Au/Cd ratios represent thermodynamically stable phase compositions for this alloy. 35,36 However, in our case, only the AuCd NCs did not aggregate in solution, while the Au 2 Cd NCs precipitated out. Most likely, for the latter NCs, the surface passivation by the surfactants present in the reaction environment was not effective enough to stabilize them in solution.…”

Metal-semiconductor nanocrystal heterostructures are model systems for understanding the interplay between the localized surface plasmon resonances in the metal domain and the relaxation of the excited carriers in the semiconductor domain. Here we report the synthesis of colloidal Au₂Cd (core)/CdSe (shell) nanocrystal heterostructures, which were characterized extensively with several structural and optical techniques, including time-resolved fluorescence and broad-band transient absorption spectroscopy (both below and above the CdSe band gap). The dynamics of the transient plasmon peak was dominated by the relaxation of hot carriers in the metal core, its spectral shape was independent of the pump wavelength, and the bleaching lifetime was about half a picosecond, comparable with the value found in the AuCd seeds used for the synthesis.

“…As far as this plane,is concerned, the Bain distortion is an extension of -3. *Apparently these authors use the designation of Bystrom and Almin for (101) the cell edges; Chang (28) interchanges their k and c so that the lattice constants increased from a to k to c; this convention has been followed here and in all references in AuCd work.…”
