Thin-film sensors based on evaporated chalcogenide glasses

Thin-film sensors based upon evaporated layers of chalcogenide glasses and sensitive to silver, copper, and lead ions have been developed. The optimal contents of the membranes were established and the electrochemical characteristics were investigated. It was shown that the sensitivity, detection li...

Zusammenfassung:Thin-film sensors based upon evaporated layers of chalcogenide glasses and sensitive to silver, copper, and lead ions have been developed. The optimal contents of the membranes were established and the electrochemical characteristics were investigated. It was shown that the sensitivity, detection limit, response time, reproducibility, and selectivity to interfering ions are in good agreement with those for traditional bulk ion-selective electrodes.
