Nonthermal Plasma Synthesis of Nanocrystals: Fundamental Principles, Materials, and Applications.

Plasma synthesis of stoichiometric Cu2S nanocrystals stabilized by oleylamine.

Nonthermal plasmas can produce high quality nanocrystals in a continuous process without requiring solvents. A nonthermal plasma process is demonstrated to synthesize stoichiometric Cu2S nanocrystals, which show no signs of oxidation by spectrophotometry after 2 months in the ambient when stabilized with oleylamine and dispersed in toluene.

Phosphorus-doped silicon nanocrystals exhibiting mid-infrared localized surface plasmon resonance.

Localized surface plasmon resonances (LSPRs) enable tailoring of the optical response of nanomaterials through their free carrier concentration, morphology, and dielectric environment. Recent efforts to expand the spectral range of usable LSPR frequencies into the infrared successfully demonstrated LSPRs in doped semiconductor nanocrystals. Despite silicon's importance for electronic and photon...

High electron mobility in thin films formed via supersonic impact deposition of nanocrystals synthesized in nonthermal plasmas.

Thin films comprising semiconductor nanocrystals are emerging for applications in electronic and optoelectronic devices including light emitting diodes and solar cells. Achieving high charge carrier mobility in these films requires the identification and elimination of electronic traps on the nanocrystal surfaces. Herein, we show that in films comprising ZnO nanocrystals, an electron acceptor t...

Nonequilibrium-Plasma-Synthesized ZnO Nanocrystals with Plasmon Resonance Tunable via Al Doping and Quantum Confinement.

Metal oxide semiconductor nanocrystals (NCs) exhibit localized surface plasmon resonances (LSPRs) tunable within the infrared (IR) region of the electromagnetic spectrum by vacancy or impurity doping. Although a variety of these NCs have been produced using colloidal synthesis methods, incorporation and activation of dopants in the liquid phase has often been challenging. Herein, using Al-doped...
