Abstract

Photoluminescence (PL) efficiency of CdTe nanocrystals was investigated as a function of the ratio of surfactant (thioglycolic acid, TGA) to Cd2+ used in aqueous preparation. When the ratio was 1.3...

5. SOLID-LIKE WATER IN CETYL ALCOHOL

Author

Norio Murase, Ikuzo Kagami, Kinji Gonda, and Shozo Koga

Subjects
chemistry.chemical_compound, Deuterium, Electrical resistivity and conductivity, Chemistry, Cetyl alcohol, Inorganic chemistry, Molecule, General Chemistry, Solid like, Thermal conduction
Abstract

Addition of a small amount of water to cetyl alcohol caused a marked increase of electrical conductivity in the α-state. Deuteron magnetic resonance spectra for the hydrated specimens indicate that the water molecules are contained in a solid-like state and enhance the protonic conduction presumably by the Grotthus mechanism.

6. Facile Preparation of Highly Luminescent InP Nanocrystals by a Solvothermal Route.

Author

Chunliang Li, Masanori Ando, and Norio Murase

Abstract

Monodisperse InP nanocrystals were prepared by a facile one-pot solvothermal route via the pyrolysis reaction between indium chloride and tris(dimethylamino)phosphine at relatively low temperatures (150-180 °C). The InP nanocrystals after size-selective precipitation had a well-crystallized zinc blende structure, a narrow size distribution, and distinguishable absorption peaks. Application of HF treatment in combination with photoetching increased their emission efficiency to 58% while their emission wavelengths were tunable from green to red. [ABSTRACT FROM AUTHOR]
