2.1. Synthesis of BaCuV2O7 nanowires
All chemicals (NH4VO3, Cu (NO3)2⋅xH2O, BaCl2, hydrochloric GPLG0634 95%, used in this study were purchased from Sigma Aldrich and used as received. In the synthesis of BaCuV2O7 nanowires, 1 mmol of NH4VO3 were dissolved in HCl/H2O = 1:2 v/v and stirred magnetically for 30 min at pH (1–2), and then 0.01 mmol of BaCl2, 0.02 Cu (NO3)2⋅xH2O mmol were mixed with the above solution and stirred magnetically for 30 min. The samples for the growth of nanowires were prepared by spin coating solution on precleaned Al2O3 and SiO2 substrates at 2000 rpm for 30 s with different thicknesses (50–150 nm) and each substrate was dried on a hot plate at 150 °C for 30 min. These samples were then placed in furnace and annealed in ambient atmosphere at 500 °C for 4 h.
