Solution-Phase Synthesis of Spherical Zinc Sulfide Nanostructures

Abstract

A facile solution-phase method has been developed to synthesize specially hollow and solid ZnS nanospheres. High-resolution TEM images on the nanospheres suggest their formation via the oriented aggregation of the primary ZnS nanocrystals. The morphology and size of the ZnS nanospheres can also be tuned easily by controlling the experimental conditions. These special spherical structures are very easily encapsulated within a uniform silica layer without any surface modification, suggesting potential applications in biochemistry and biodiagnostics.

Effect of Mn doping on structural, optical and photocatalytic behaviors of hydrothermal Zn1−xMnxS nanocrystals

“…SEM images revealed (Fig. 2) the rough surface of these microspheres that are composed of several smaller particles with an average diameter of the order of nm when observed at higher resolution in accordance with the reported results of ZnS microstructures [22,23]. Fig.…”

Novel silica‐coated iron–carbon composite particles and their targeting effect as a drug carrier

“…Absorption bands at 462 (Si-O-Si band), 798 (Si-O-Si symmetric strength), and 1083 cm 21 (Si-O-Si antisymmetric strengths) were observed after SiO 2 coating. 20,21 The data suggested strongly that the iron-carbon composite particles were really encapsulated within the silica matrix. The BET surface area of silica-coated iron-carbon composite particles was estimated to be 264.16 m 2 /g, which is considerably large since the Fe particles have been included in the calculation.…”

Preparation and microwave absorption of porous hollow ZnO by CO2 soft-template

“…Some groups [22][23][24] have reported that hollow CaCO 3 , CoOOH and ZnS could be successfully prepared by using CO 2 , O 2 and H 2 S bubble as soft templates. Under the conditions of our experiments, the following reactions are thought to be occurred in the process of porous hollow ZnO…”
