“…Different techniques are used to synthesize V 2 O 5 NFs such as simple solution chemistry route [30], sol-gel method [31][32][33], annealing an ammonium vanadate compound [34], a high-temperature phase transition in nitrogen and air [35] and the solution combustion method [36]. Although the sol-gel method is widely used, due to the possibility of agglomeration, the sputter method can be considered as an alternative to obtain better quality films.…”

In this study, V2O5 nanoflakes (NFs) was coated on Si substrate by DC sputtering to obtain V2O5 NFs/n-Si heterojunction. To utilize V2O5 NFs as a broadband photodetector, absorbance spectra were studied using UV−Vis−near-IR (NIR) spectroscopy. Cut-off wavelength was 530 nm. Furthermore, EDX, XRD, XPS and SEM analyses of V2O5 NFs were achieved. The V2O5 NFs/n-Si device gave a very high rectifying ratio of 1.18×104 in the dark and at zero bias, it has self-powered mode and an on/off ratio of 1.29×106. Optical analyses of the V2O5 NFs/n-Si heterojunction device were studied in detail under UV (365, 395 nm) and IR (850 nm) illumination as well as visible light with varying light intensities. Analysis of experimental studies showed that the device has a high photoresponse under all illuminations. For optical analysis based on I-V measurements, responsivity, detectivity, on/off ratio, EQE, NPDR and NEP analyses were achieved. The maximum values of responsivity from measurements under visible, UV (395 nm) and IR illumination (850 nm) were 104, 882 and 850 mA/W for -2.0 V, respectively. Detectivity values are maximized at V=0 volts and are 6.84×1011, 7.87×1012 and 6.87×1012 Jones for the same illuminations respectively. With increasing intensity, the rectification ratio and NEP decreased while the other parameters generally increased. The increase in performance at increasing visible intensity was attributed to the increase in photogenerated carrier density at high intensities, and the high performance in the UV region was attributed to the high light absorption of V2O5 NFs in the UV region.

Solution combustion synthesis (SCS) has been widely used to produce simple and complex oxides with a desired morphology (size and shape). SCS is valuable due to low cost, simplicity and energy efficient synthesis. To guarantee the best molecular‐level mixing of reactants in an aqueous or solvent‐based solution some parameters need to be controlled, such as fuel type, metal cations precursors, stoichiometry ratio (φ), pH effect, atmosphere and initiation type. These determine the final properties of the oxide materials, providing the potential to reach different morphologies, which are essential for their final applications. This Review article focuses on the crucial parameters in SCS and how these affect the overall materials properties from nanostructures to thin films. To finalize, special attention is given to the application of SCS to form metal oxide thin films at low temperature and their application in thin film transistors (TFTs).
