Room-Temperature Synthesis and Characterization of Highly Monodisperse Transition Metal-Doped ZnO Nanocrystals

Singh S.P., Perales-Perez O., Tomar M.S., Parra-Palomino A., Ruiz-Mendoza A., University of Puerto Rico, PR

We present here the results of our current efforts on size-controlled synthesis of bare and Mn- and Co-doped ZnO nanocrystals. Stable suspensions of these materials were produced in ethanol solutions at room-temperature. XRD characterization of [...]

Gas-phase Production of Monodisperse Ferroelectric Nanoparticles

Seol K.S., Tomita S., Takeuchi K., Katagiri T., Miyagawa T., Ohki Y., RIKEN, JP

Laser ablative technology was used to prepare monodisperse nanoparticles (4-20 nm in diameter) of lead zirconate titanate (PZT). Laser ablation of a PZT ceramic target in oxygen ambience produced amorphous and irregularly-shaped PZT nanoparticles. A [...]
