“…Chalcogenide glass sensors for determination of heavy-metal ions are well known. Moreover, microelectronics has allowed the miniaturization and integration of such micro sensors [6,7]. As major advantages of these amorphous inorganic materials we emphasize that they can be easily prepared in bulk or layered forms by various methods.…”

Cadmium chalcogenide thin films were deposited by different processes. Pulsed laser deposition, thermal evaporation, and sputtering were used to elaborate micro devices on glass substrate from CdS-AgI-Ag2S-As2S3, CdS-Ag2S-Sb2S3 and Cd-Ag-As2S3 starting materials respectively. The micro films were characterised using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and electrochemistry. Comparative structural characterisation leads us to understand sensors out-put signal. The best miniaturised sensor was selected. The very first electrochemical results are presented. The potentiometric response of Cd-Ag-As2S3 sensing matrix showed a quasi-Nernstian behaviour with a great detection limit. Moreover Cd-ISE is sensitive to silver (+I) in solution.

“…The composition of glass Ge-S-AgI bulk and thin film samples was determined by Auger spectroscopy (AES) using LAS 3000 Riber system. The concentration profiles of the layers were performed utilizing Ar ion gun (CI 40) [10]. A semi-quantitative evaluation is performed with the elemental sensitivity factors.…”

The novel bulk glasses from the chalcohalide Ge-S-AgI system have been synthesized. From the as-prepared samples amorphous films have been deposited by vacuum thermal evaporation. The amorphous nature of the studied bulk and layered materials has been proved by Xray diffraction. The composition of the synthesized bulk chalcohalide glasses and corresponding amorphous thin films has been ascertained by means of Auger electron spectroscopy. The morphology and uniformity of the deposited layers have been investigated using scanning electron microscopy. The basic optical properties of the studied glassy films have been defined. Variations in the optical behaviors as a function of the composition have been derived. Experiments related to optical recording in the investigated Ge-S-AgI layers has been implemented. The diffraction efficiency as a function of various recording beam intensities has been obtained.
