Onion slice shaped assembled ZnS quantum wires

Abstract

Ultra-narrow wurtzite ZnS quantum wires assembled towards an onion slice shape are synthesized in water using a simple hydrothermal procedure. Wires are formed through an oriented attachment mechanism from wurtzite ZnS spherical particles. Strong confinement effect originated from the narrow width was observed and holds promise for use in broad optoelectronic device application.

A study on the synthesis, longitudinal optical phonon–plasmon coupling and electronic structure of Al doped ZnS nanorods

“…8,9 In the last two decades, much attention has converged on the synthesis of one-dimensional (1D) nanostructured materials, such as nanorods, 10,11 nanowires, 12,13 nanoribbons, 14 and nanotubes. 15 These have been synthesized by various techniques such as the chemical co-precipitation method, 10 hydrothermal method, [16][17][18][19][20] thermal evaporation method, 21 pulsed laser deposition, 22 electrochemical deposition, 23 molecular beam epitaxy (MBE), 24 microwave assisted techniques, 25 chemical vapor deposition 26 etc. This interest is due to their unique properties and applications, which were superior to those of their bulk counterparts.…”

Nanoparticle heterojunctions in ZnS–ZnO hybrid nanowires for visible-light-driven photocatalytic hydrogen generation

“…[8][9][10][11][12][13] The construction of a variety of ZnS-ZnO nanocomposites in the form of nanotubes, 14,15 nanorods, 15,16 nanobelts, [17][18][19] nanosheets, 20 multipods 21 and quantum dots 22 have been widely reported. Both ZnO and ZnS contain only earth-abundant elements, and are theoretically not active in the visible region due to the wide direct band gap (E g = 3.4 eV for ZnO and E g = 3.7 eV for ZnS).…”

Novel microwave assisted synthesis of ZnS nanomaterials

“…[6][7][8][9][10][11][12] Cubic blende ZnS has been synthesized in a number of ways including by precipitation, by hydrothermal synthesis, and using ultrasonic irradiation. 13,14,15 Using these techniques for large scale synthesis limits the applications of ZnS as a photocatalyst due to the high cost, difficulty in separation, recovery and recycling in industrial environments. Some of these reactions also require high temperatures and the use of H 2 S as a starting material.…”
