Broad range tuning of structural and optical properties of Zn_xMg_1−xO nanostructures grown by vapor transport method

Tunable nonlinear absorption and optical limiting behavior of NaBi(MoxW1−xO4)2 single crystals with ratio of Molybdenum/Tungsten

“…It is possible to design a device emitting specific light within this region by adjusting the composition. The studies on Zn x Mg 1−x O indicated that crystal structure and emission characteristics change depending on the composition [19]. It was reported in [19] that Mg-rich compounds may be used to design optoelectronic devices operating at deep UV range.…”

Vapor-Transport Synthesis and Annealing Study of ZnxMg1–xO Nanowire Arrays for Selective, Solar-Blind UV-C Detection

“…4−6 Substitutional doping of Mg with ZnO, on the other hand, has been described as a means of engineering the bandgap of a ternary Zn x Mg 1– x O system as high as a 5.8 eV for solar-blind photodetectors. 7−10 Although Mg has been reported as a feasible dopant to ZnO (due to the similar ionic radii of Zn 2+ and Mg 2+ ), 11,12 Mg/ZnO alloy systems have also shown to phase segregate for high Mg content. 13 Thus, the development of reliable techniques toward synthesizing aligned ZnO nanowires, and appreciably incorporating Mg during synthesis is of great significance.…”

“…Ultraviolet, solar-blind communication systems that exploit atmospheric scattering to propagate signals toward a nonline of sight receiver (with ranges on the order of kilometers) have been examined extensively, yet the detectors in these receiver systems have largely been dominated by bulky and costly photomultiplier tubes. − Semiconductor-based deep-UV detectors have consequently become of great interest due to their potential advantages of producing low-cost, low-power-consumption, highly scalable solutions. Although ZnO nanowire (NW)-based photodetectors have been heavily investigated, this material system only exhibits a cutoff detection corresponding to the band-edge energy of ZnO in the UV-A spectrum (3.10–3.94 eV). − Substitutional doping of Mg with ZnO, on the other hand, has been described as a means of engineering the bandgap of a ternary Zn x Mg 1– x O system as high as a 5.8 eV for solar-blind photodetectors. − Although Mg has been reported as a feasible dopant to ZnO (due to the similar ionic radii of Zn 2+ and Mg 2+ ), , Mg/ZnO alloy systems have also shown to phase segregate for high Mg content .

“…Thus, the development of reliable techniques toward synthesizing aligned ZnO nanowires, and appreciably incorporating Mg during synthesis is of great significance. Prior work investigating ZnMgO nanostructures have been reported based on deposition methods, which have ranged from: molecular beam epitaxy, metal–organic chemical vapor deposition, , pulsed-laser deposition, hydrothermal techniques, , radio frequency magnetron cosputtering, and vapor-phase transport. ,, The vapor-phase transport technique yields highly crystalline nanostructures and is a relatively straightforward synthesis route, able to encompass equilibrium formation in one step, rather than necessitating ex situ incorporation. Additionally, understanding the changes in optical and physical properties due to postgrowth thermal treatment of ZnMgO nanowires is of importance toward tuning the cutoff wavelength for solar-blind photodetectors.…”
