Near-infrared luminescence from small gold nanocrystals
Article Abstract:
A novel photoluminescence is reported for small metal nanocrystals in the near-infrared region (1.1-1.6 Mum) where near-infrared photoluminescence spectra were measured at room temperature for 1.1 and 1.7 nm Au nanocrystals using a 1.06 Mum excitation source. This photoluminescence is attributed to sp to sp-like transitions, analogous to intraband transitions in bulk gold, however, the exact mechanism is unknown.

CeO2 nanorods and gold nanocrystals supported in CeO2 nanorods as catalyst
Article Abstract:
Large-scale well-crystallized CeO2 nanorods with uniform diameters in the range of 20-30 nm and lengths up to tens of micrometers are first synthesized through a hydrothermal route in 5 M KOH solution at 180 degree Celcius for 45 h without any templates and surfactants. The synthesized Au/CeO2 nanorods demonstrate a higher catalytic activity in CO oxidation than the pure CeO2 nanorods.

DNA-controlled assembly of protein-modified gold nanocrystals
Article Abstract:
The study is done on the controlled assembly in solution of gold nanocrystals modified by attachment of complimentary protein-DNA conjugates. The study reveals that the rate of formation of the resulting aggregates can be controlled by varying the salt and modified nanocrystal concentrations.
