以LaF 3单晶为电极材料，以聚3，4-乙撑二氧噻吩（PEDOT）为固体接触层，制备了全固态氟离子选择性电极（伊势）。与基于聚合物的ISE相反，基于结晶膜的ISE尚未用于全固态器件，从而禁止将ISE集成在芯片上。与传统的内部填充溶液伊势相比，本研究开发的全固态氟化物伊势具有上级的灵敏度（−56.0±0.9 mV/dec）和选择性。利用计时电位法和电化学阻抗谱分析了PEDOT作为固体接触层的作用，结果表明PEDOT提高了电极的稳定性。全固态设备可以使氟化物伊势稳定化，并促进环境，工业，农业和生理监测。
An all‐solid‐state fluoride ion‐selective electrode (ISE) was prepared using LaF3single crystal with poly(3,4‐ethylenedioxythiophene (PEDOT) as the solid contact layer. In contrast to polymer‐based ISEs, crystalline membrane‐based ISEs have not been used for all‐solid‐state device, thereby prohibiting the integration of ISEs on a chip. The all‐solid‐state fluoride ISE developed in this study exhibited superior sensitivity (−56.0±0.9 mV/dec) and selectivity compared to those of conventional inner filling solution ISE. The effects of PEDOT as a solid contact layer were analyzed using chronopotentiometry and electrochemical impedance spectroscopy, which revealed that PEDOT promoted electrode stability. The all‐solid‐state device can miniaturize the fluoride ISE and facilitate environmental, industrial, agricultural, and physiological monitoring.
