摘要:
We fabricated a silver ion emitter based on the solid state electrolyte film of RbAg4I5 prepared by pulsed laser deposition. The RbAg4I5 target for PLD process was mechano-chemically synthesized by high-energy ball milling in Ar atmosphere using β-AgI and RbI as raw materials. The ion-conducting properties of RbAg4I5 were studied by alternating current (AC) impedance spectroscopy and the ionic conductivity at room temperature was estimated 0.21 S/m. The structure, morphology, and elemental composition of the RbAg4I5 film were investigated. The Ag+ ion-conducting property of the prepared superioni-conductor film was exploited for ion-beam generation. The temperature and accelerating voltage dependences of the ion current were studied. Few nA current was obtained at the temperature of 196 ℃ and the accelerating voltage of 10 kV.
