Microwave-Assisted Synthesis and the Surface Modification of 1-D Dimensional ZnS:Mn Nanocrystals for Polymer Applications

Abstract

A b s t r a c tIn recently years one-dimensional (1D) nanostructures (wires, rods, tubes) have received much attention because of two-dimensional quantum confinement effect and their potential application in optoelectronics devices, such as photovoltaic solar cells or light emitting diodes. In this context one of the most important is zinc sulfide (ZnS) nanocrystal materials.ZnS is a large band gap II-VI group compound, which has two structural polymorphs: cubic zinc blende (3.72 eV) or hexagonal wurtzite (3.77 eV). Typically one-dimensional ZnS nanocrystals are characterized by wurtzite structure. ZnS has been targeted as an efficient semiconductor host to dope different transition metal ions such as Mn or Cu. ZnS doped with Mn is a luminescent material well known for its photoluminescence, electroluminescence and cathodoluminescence. In this article we present the microwave solvothermal synthesis of 1D ZnS:Mn nanocrystalline and their surface modification for polymer application.

Hydrothermal Synthesis of Bismuth Ferrite Hollow Spheres with Enhanced Visible-Light Photocatalytic Activity

“…By careful control of reaction parameters undesirable side reactions or phase transformations are minimized and lead to reduced defects as well as enhanced reaction rate and scaleability. Thus, this method is widely used to synthesize hollow spheres [ 12 , 13 ], one-dimensional materials such as tubes and wires [ 14 , 15 ], two-dimensional materials [ 16 , 17 ], and heterostructured materials [ 18 , 19 ].…”
