Quantum-confined GaN nanoparticles synthesized via liquid-ammonia-in-oil-microemulsions.

چکیده
GaN nanoparticles, 3-4 nm in size, are synthesized in a microemulsion using liquid ammonia as the polar droplet phase. Surprisingly, GaN is readily crystalline although prepared at -40 °C. The nanoparticles show a band gap of 4.4 eV as well as light emission with its maximum at 336 nm. Both confirm the expected quantum-confinement effect.

Formation of hollow silica nanospheres by reverse microemulsion.
Uniform hollow silica nanospheres (HSNs) synthesized with reverse microemulsion have great application potential as nanoreactors because enzymes or nanocatalysts can be easily encapsulated de novo in synthesis. Water-in-oil (w/o) reverse microemulsions comprising the polymeric surfactant polyoxyethylene (5) isooctylphenyl ether (Igepal CA-520), ammonia and water in a continuous oil phase (alkan...
متن کاملSurfactant ionic liquid-based microemulsions for polymerization.
Surfactants based on imidazolium ionic liquids (ILs), including polymerizable surfactant ILs, have been synthesized and used to stabilize polymerizable microemulsions useful for producing polymer nanoparticles, gels, and open-cell porous materials.
متن کاملSynthesis of high-coercivity cobalt ferrite particles using water-in-oil microemulsions
Magnetic nanoparticles of cobalt ferrite (CoFe204) have been synthesized using water-in-oil microemulsions consisting of water, cetyl trimethyl ammonium bromide (surfactant), n-butanol (cosurfactant), and n-octane (oil). Precursor hydroxides were precipitated in the aqueous cores of water-in-oil microemulsions and these were then separated and calcined to give the magnetic oxide. X-ray diffract...
متن کامل3D GaN Structures with Reduced Piezoelectric Fields For Efficient Quantum Well Emission
A fabrication method for the formation of 3D GaN structures with reduced piezoelectric field is presented. Via optimized selective epitaxy the surface is just composed of hexagonally patterned semipolar {11̄01} or {112̄2} planes. GaN growth with less NH3 at a higher growth speed, a doubled effective area and good light outcoupling properties compared to c-plane growth are additional advantages of...
متن کاملWavelength and polarization variations of InAs/GaAs quantum dots emission at liquid Helium temperature via microphotoluminescence spectroscopy
In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...
