Abstract [en]

Dense homogeneous fabric composed from continuous bead-free erbium-doped sodium potassium niobate (Er:NKN) 100 μm long and 100-200 nm in diameter nanofibers was sintered by sol-gel calcination assisted electrospinning technique. Er doping with the concentration of 2 at.% provides readily detectable room-temperature broad-band photoluminescence (PL) centered at λPL = 0.55 and 0.98 μm being pumped, respectively, with 532 and 785 nm lasers. Electric field induced resistance switching and strong electric rectification effect were found in nanoporous sandwich Au/Er:NKN/Pt capacitive cell. Memristor-type current-voltage I-V characteristics originate from the electrochemical migration of oxygen vacancies at the n-type Er:NKN oxide/high work function Pt cathode junction interface.
