Special Issue Information

Dear Colleagues,

Gas sensors have extensive applications, especially for environmental monitoring, medical and healthcare applications, and so on. Thin film gas sensors can be integrated into advanced portable devices with more applications; therefore, they have attracted great interest; the development of gas sensors is advancing year on year. In the view of operation mechanisms, the types of gas sensors can be classified into semiconductors, catalytic, photoionization, etc. In the view of devices, gas sensors can be packaged into portable devices and fixed sensors. Typically, portable detectors that can be hand-held, worn on clothing, or on a belt/harness, can monitor the atmosphere around people and have a great market. To meet the various demands of gas sensors, there are still a lot of challenges and opportunities. The contribution and collaboration of researchers in different areas appear very important. This Special Issue aims at reporting original research and reviews, focusing on advanced thin film gas sensors, to provide readers with an overall picture and the most up-to-date findings in the field.

In particular, the topics of interest include, but are not limited to:

  • Sensor materials
  • Sensors with multiple functions
  • Design, synthesis and characterization
  • Thin film deposition for sensors
  • Computation for sensor or sensor materials
  • Sensor testing
  • Sensor fabrication

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. Coatings is an international peer-reviewed open access monthly 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.

The paper presents the results of an investigation of the nanostructure, elements, and phase composition of thin (100–140 nm) tin dioxide films obtained via magnetron sputtering and containing Ag, Y, Sc, Ag + Y, and Ag + Sc additives in the volume. Electrical and gas‐sensitive characteristics of hydrogen sensors based on these films with dispersed Pt/Pd layers deposited on the surface were studied. The additives had a significant effect on the nanostructure of the films, the density of oxygen adsorption sites on the surface of tin dioxide, the band bending at the grain boundaries of tin dioxide, the resistance values in pure air, and the responses to hydrogen in the concentration range of 50–2000 ppm. During the long‐term tests of most of the samples studied, there was an increase in the resistance of the sensors in clean air and in the response to hydrogen. It has been established that the joint introduction of Ag + Y into the volume of films prevents the increase in the resistance and response. For these sensors based on thin films of Pt/Pd/SnO2:Sb, Ag, Y the responses to 100 and 1000 ppm of H2 are 25 and 575, correspondingly, the response time at exposure to 100 and 1000 ppm of H2 are 10 and 90 s, the recovery time at exposure to 100 and 1000 ppm of H2 17 and 125 s. Possible mechanisms of the effect of additives on the properties of sensors and the stability of their parameters during long‐term operation were considered. Full article
