摘要

Pure and In-doped ZnS structures have been grown using a VS method. Thermal treatments have been performed at temperatures ranging from 1000 to 1200 °C, during 15 to 17 hours in a N2 overpressure environment. Nanowires and nanoribbons are the main kind of structures obtained for pure ZnS, depending on the deposition temperature. In the case of ZnS:In, nano- and microswords, nanoribbons, hierarchical structures and nanoplates are obtained, depending on the In content in the starting material and on the deposition temperature. Nanoplates are the dominant structures for the higher In content. The influence of the impurity incorporation on the morphology of the structures has been studied by transmission electron microscopy. While in pure ZnS wires and ribbons two main growth directions are observed ([0001] and [100]), indium doped structures show a greater variety of morphologies associated with different growth behavior.

CrystEngComm is the forum for the design and understanding of crystalline materials. We welcome studies on the investigation of molecular behaviour within crystals, control of nucleation and crystal growth, engineering of crystal structures, and construction of crystalline materials with tuneable properties and functions. We publish hypothesis-driven research into… how crystal design affects thermodynamics, phase transitional behaviours, polymorphism, morphology control, solid state reactivity (crystal-crystal solution-crystal, and gas-crystal reactions), optoelectronics, ferroelectric materials, non-linear optics, molecular and bulk magnetism, conductivity and quantum computing, catalysis, absorption and desorption, and mechanical properties. Using Techniques and methods including… Single crystal and powder X-ray, electron, and neutron diffraction, solid-state spectroscopy, spectrometry, and microscopy, modelling and data mining, and empirical, semi-empirical and ab-initio theoretical evaluations. On crystalline and solid-state materials. We particularly welcome work on MOFs, coordination polymers, nanocrystals, host-guest and multi-component molecular materials. We also accept work on peptides and liquid crystals. All papers should involve the use or development of a design or optimisation strategy. Routine structural reports or crystal morphology descriptions, even when combined with an analysis of properties or potential applications, are generally considered to be outside the scope of the journal and are unlikely to be accepted.
