Layered double hyroxide-CdSe quantum dot composites through colloidal processing: Effect of host matrix-nanoparticle interaction of optical behavior
Article Abstract:
Layered double hydroxide (LDH)-monodispersed 4-nm CdSe nanoparticle composites were prepared through restacking of layers of colloidally dispersed delaminated LDH in the presence of CdSe nanoparticles in 1-butanol. The composites exhibit a blue shift for CdSe absorption and the observed blue shift is due to the interaction of the quantum dots with the LDH layers, which leads to surface modifications of the nanoparticles.

Ferrimagnetic nanogranular Co3O4 through solvothermal decomposition of colloidally dispersed monolayers of alpha-cobalt hydroxide
Article Abstract:
Co3O4 nanoparticles of 35 nm with a cauliflower-like morphology are obtained when a monolayer colloidal dispersion of dodecyl sulfate intercalated alpha-cobalt hydroxide in butanol is subjected to solvothermal hydrolytic decomposition. These particles exhibit weakly ferromagnetic properties in contrast with both bulk and dispersed nanoparticulate Co3O4.

Optical properties and two-dimensional electronic structure in wide-gap layered oxychalcogenide: La2CdO2Se2
Article Abstract:
Epitaxial thin films prepared by a reactive solid-phase epitaxy were used to investigate the optical electronic properties of a wide-gap layered oxyhalcogenide, LaCdO2Se2. The two-dimensional crystal structure that remarkably reduces bandwidth of the conduction band was a major origin for the wide band gap.
