WebDec 1, 2024 · With the use of rGO-Ag H designed in a very simple manner, the Raman spectral detection of tellurium(IV) becomes possible despite its complex nature in aqueous solution. A detection limit of about 100 nM is achieved at pH 5.50. According to the similar chemical behaviour of Po(IV) and Te(IV) in aqueous solution, it can be assumed that the … WebMar 28, 2006 · Based on density functional perturbation theory, we have studied the vibrational properties of three crystalline phases of tellurium dioxide: paratellurite α − TeO 2, tellurite β − TeO 2, and the new phase γ − TeO 2, recently identified experimentally. Calculated Raman and IR spectra are in good agreement with available experimental data.
WebOct 25, 2024 · The photocurrent in tellurium nanowire (Te NW) exhibits a subtle influence by many extrinsic factors. Herein, we fabricate Te NW devices and explore their photoresponse properties in detail. It is observed that the current increases greatly at low environmental relative humidity (RH) under light illumination, demonstrating an evident … WebTransparent tellurite glasses can be achieved by combining the vitrified tellurium oxide (TeO2) host with various modifier oxides of Zinc (ZnO), Sodium (Na2O), Silicon (SiO2), etc. over a wide composition range. ...
