Halide‐Transport Chemical Vapor Deposition of Luminescent ZnS:Mn²⁺ One‐Dimensional Nanostructures

Abstract

ZnS:M2+ (M = Mn, Co, or Cu) single‐crystal one‐dimensional nanostructures have been prepared via a simple halide‐transport chemical vapor deposition (HTCVD) process at a relatively low temperature. The obvious phase transition suggests that doping with Mn favors the formation of the hexagonal phase at a relative low temperature. The strong photoluminescence from blue to green and the yellow–orange emission, which was caused by the doping of various elements in ZnS nanowires and nanobelts, suggests possible applications of the one‐dimensional nanostructures in nanoscale optoelectronic devices.

Optimized doping concentration of manganese in zinc sulfide nanoparticles for yellow-orange light emission

“…6b and f, which have been observed by many groups [15,[31][32][33][34]. Three mechanisms can be used to explain the red shift: first, it may be due to the high density of surface states or strong electron-phonon coupling effects [31,33,34].…”

Structure, optical and magnetic characterizations of Mn doped ZnS dilute magnetic semiconductor synthesized by mechanical alloying

“…46 1. Introduction 51 Zinc sulfide being a wide band gap II-VI semiconductor is an 52 important host material for producing commercial phosphors [1] 53 having valuable properties such as photoluminescence (PL) [2], 54 electroluminescence [3,4] and thermal luminescence [5], which 55 make it a potential candidate for various high-performance devices 56 and displays [6]. Many new aspects of ZnS can be introduced by 57 controlling its different spin states if the lattice is doped with tran- 58 sitional metal Mn, to make it a DMS.…”

Symmetry and electronic states of Mn2+ in ZnS nanowires with mixed hexagonal and cubic stacking

“…The transition metal dopants exhibit promising properties as potentially attractive building block for nanoscale spintronic, electronic, magnetic, optoelectronic, and photonic devices. [3][4][5][6][7][8] ZnS is considered to be a particularly suitable host for transition metal ion incorporation due to its wide band gap ͑ϳ3.6 eV at room temperature͒ and Mn 2+ or Cu 2+ -doped ZnS is already used extensively as phosphors for displays and in electroluminescent devices. 9 Multiple efforts have been focused on the fabrication of the ZnS: Mn 2+ nanowires using various techniques.…”

“…9 Multiple efforts have been focused on the fabrication of the ZnS: Mn 2+ nanowires using various techniques. 6,10 Nevertheless, the dimensions of most of these one-dimensional ͑1D͒ nanostructures are typically larger than the exciton Bohr radius in bulk ZnS, which makes the quantum confinement effects rarely observable. Since the optical and magnetic properties of Mn 2+ in DMS essentially rely on their actually occupied symmetry sites and the electronic structures in the host materials, ESR has been employed as an atomic probe to study the local crystal field effects and symmetry around Mn 2+ impurities.…”
