Mercury Ion Selective Thin Film Sensor Prepared by Pulsed Laser Deposition Technique
This paper presents a method for preparing mercury ion selective thin film sensor. Pulsed laser deposition (PLD) technique was used to prepare thin film on the surface of light-addressable potentiometrie sensor (LAPS). Material sensitive to mercury ion was synthesized by two-step solid phase reaction and as target of PLD. After LAPS was prepared, the target material was ablated by PLD and deposited the surface of the LAPS. The deposited LAPS chip was cut and prepared thin film sensor (Hg-LAPS). A novel measuring unit including Hg-LAPS, reference electrode (RE) and LED was designed. The Hg-LAPS has a high sensitivity towards mercury (Ⅱ) ion and shows good repetition and stability. The detection limit of the thin film sensor is 3×10-6 mol/L and the response time is less than 2 rain. interfering ions, pH, lifetime and hysteresis etc. are also investigated.
