Thin chalcogenide films prepared by pulsed laser deposition – new amorphous materials applicable in optoelectronics and chemical sensors

“…of the Ga-La-S [19,50], Ag-As-S, Pb-Ag-As-I-S, Cd-Ag-As-I-S, Ge-Ga-S-Cs-I, Cu-Ag-As-Se-Te, PbS-AgI-As-S, CdS-AgI-As-S, Tl-Ag-As-I-S, Cu-Ag-As-Se-Te, Ag-I-As-S, Ag-I-AsSe and other (pure and doped with Pr 3+ ions) systems (e.g. [3][4][5][6][15][16][17]19,[24][25][26][28][29][30][31][32][33]49,50,52,57,59,61,71,76,78,104,105,107]). Many of them have been used as ion-selective membranes, ion selective sensors, electronic tongue [26] or as light emission materials.…”

“…The physico-chemical properties of prepared films were close to the properties of target glasses. The high sensitivity ion-selective membranes prepared from such films were used for determination of Pb 2+ , Cd 2+ , Tl + , Hg 2+ , Fe 3+ , Ni 2+ , Zn 2+ , Ca 2+ , Mg 2+ and other ions [24][25][26]29,30]. The detection limits were as low as 10 À6 -10 À7 mol/l [6,32].…”

“…from Cu-Ag-As-Se-Te, Cu-Ag-As-Se, Pb-Ag-As-I-S, Cd-Ag-As-I-S, Te-AgAs-I-S, Ag-I-As-S, Ag-I-As-Se, Ag-As-Te-Se and other systems [3][4][5][6]24,25,30,32]. Thin films of such complex chalcogenides form ion sensitive membranes, as we have already mentioned.…”

AES study of ion-selective membranes based on chalcogenide glasses

“…Chalcogenide glass sensors for determination of heavy-metal ions are well known [1] and successfully applied in industrial and environmental pollution control [2]. Moreover, microelectronics has allowed the miniaturization and integration of such sensors and the development of multi-sensor systems for simultaneous detection of several chemical species [3].…”
