Special Issue Information
Dear Colleagues,
A number of physical/chemical properties of materials change drastically as the size of the system decreases down to the nanometer scale. Zinc oxide (ZnO) is among the materials that can be used to exploit the beneficial consequences of nanoscale as it can be grown into a surprising variety of morphologies with the one-dimensional structure being the dominant one. Since the first breakthrough investigations of ZnO nanostructures—commenced around 2001 after the discovery of ZnO nanowire lasing and the growth of ZnO nanobelt ‑ this material continues to fascinate researchers owing to the advantages it offers over its nanoscale rivals, i.e., other metal oxide semiconductors. In addition, devices based on nanostructured ZnO hava shown documented performance in a wide range of applications including photonics, optoelectronics, gas sensors and biosensors, photodetectors, photocatalysis for wastewater treatment, energy conversion devices and so on. Although a great deal of efforts has been undertaken in this area, major challenges still remain to be tackled.
This Special Issue of Materials, titled “ZnO-Based Nanomaterials and Devices: Fundamental and Applications”, aims at gathering together a collection of articles (regular and reviews) focusing at both the scientific and technological aspect of ZnO nanomaterials. We expect to create a focus issue that will serve not only as a summary of the current state-of-the-art in the field concerning the growth and application of nanostructured ZnO, but will further provide insightful aspects on the future and prospects of ZnO-based hybrid combinations with other nanomaterials over a broad discipline of applications that this material can meet.
Covering a wide range of activities, topics include, but are not limited to:
- Controlled synthesis of ZnO nanowires arrays, nanoparticles, quantum dots, etc., by wet chemistry, high-temperature thermal evaporation methods, molecule beam epitaxy pulsed laser deposition and so on.
- Hybrid nanostructures of ZnO with other functional materials with enhanced properties.
- Energy conversion devices (e.g., dye-sensitized solar cells, electrochemical and photo-electrochemical devices for water splitting).
- Novel morphologies and large scale synthesis of ZnO nanoparticles for efficient photocatalytic degradation of water pollutants.
- Piezoelectric energy harvesting of ZnO nanostrucres.
- Bio-based applications of ZnO nanoparticles.
- Simulation of electronic, optical, magnetic, vibrational properties, etc.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
