In detail, single crystal WSe₂ is codoped with 4 at% Co and various concentrations of Nb by employing the physical ion implantation method. Raman, X-ray diffraction and X-ray photoelectron spectroscopy results reveal the effective substitutional doping of implanted elements (Co and Nb). Magnetic measurements illustrate that both un-doped and 4 at% Co doped WSe₂ show weak ferromagnetism whereas magnetization is strongly enhanced when Co and Nb are codoped into WSe₂. The magnetization is comparable with a ferromagnet, which may be attributed to Co, Nb doping and defects. In addition, a large coercivity of ≈1.2 kOe is observed in the 1 at% Nb–4 at% Co codoped WSe₂ sample, which may be ascribed to the combined effect of doping-induced stress, defect-dictated pinning and anisotropy of Nb-Se bond owing to the charge transfer between Nb and Se ions.]]> Tue 05 Jul 2022 11:09:36 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44420 Thu 13 Oct 2022 09:37:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46662 3N₄) has attracted much attention due to its unique properties and excellent performance in the field of sensors, which has inspired the authors to compile this review. Although there are many reviews on the synthesis and applications of g‐C₃N₄ materials, a targeted, systematic, comprehensive summary of applications in sensors and the sensing mechanisms of g‐C₃N₄‐based nanomaterials are not published. In this review, the preparation methods and synthetic conditions for preparing g‐C₃N₄ with different morphologies, such as conventional bulk g‐C₃N₄, g‐C₃N₄ nanosheets, and g‐C₃N₄ quantum dots, are introduced in detail. By reviewing recent advances in g‐C₃N₄‐based nanomaterials in ion sensors, biosensors, gas sensors, and humidity sensors, this study provides more comprehensive and in‐depth information for the further design of g‐C₃N₄‐based sensors with enhanced performance. A brief outlook of g‐C3N4‐based sensors is presented as the conclusion of this review.]]> Mon 28 Nov 2022 18:25:37 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50823 Fri 18 Aug 2023 11:02:55 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53216 Fri 17 Nov 2023 11:40:06 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52950 Fri 03 Nov 2023 11:04:40 AEDT ]]>
