Název v původním jazyce

Chalcogenide glasses of Ge-Ga-Sb-S system doped with Er3+, Ho3+ and Nd3+/Tm3+

Popis výsledku v původním jazyce

Chalcogenide glasses of Ge-Ga-Sb-S are suitable materials as a host matrix for doping with rare earth elements [1]. The applications of such materials can be found in telecommunication, laser devices, photon converters etc. [2-4]. Prepared Ge-Ga-Sb-S glasses were doped with Er3+, Ho3+ and co-doped with Nd3+/Tm3+ ions. The amorphous state of prepared samples was studied by X-ray diffraction (XRD) analysis. Composition was determined by energy dispersive X-ray (EDX) spectroscopy. The glass transition as well as crystallization temperature were studied via differential scanning calorimetry (DSC). Spectral dependence of refractive index and optical band gap energy were calculated from data of variable angle spectroscopic ellipsometry (VASE). Photoluminescence (PL) spectroscopy was used for study of 4f-4f electronic transitions of rare earth elements. In cases of glasses doped with Er3+ were observed 4I13/2?4I15/2 (1540 nm), 4I11/2?4I15/2 (990 nm) transitions and up-conversion of 4F9/2?4I15
