Popis: | Potentiometric thin film sensors on the basis of the two different chalcogenide glass materials Ag-As-S and Cu-Ag-As-Se-Te have . been prepared by means of the pulsed laser deposition PLD technique onto SirSiO substrates with an additional contact layer of 2 CrrAu and TirPt, respectively. The physical layer structure and the stoichiometric composition of the deposited glass materials have . . been investigated by means of Rutherford backscattering spectrometry RBS and transmission electron microscopy TEM . Depending on the material systems used, in a conventional Atwo-electrodesB measuring set-up, these novel thin film sensors possess a high sensitivity . . . . towards lead 23-25 mVrpPb , copper 29-31 mVrpCu , cadmium 23-27 mVrpCd and silver about 54 mVrpAg over a measuring period of more than 60 days. The obtained results are in good accordance when comparing them to measurements performed with conventional bulk ion-selective electrodes, built-up of the same layer composition. q 2000 Elsevier Science S.A.
