Popis výsledku v původním jazyce

The AgAsS2 glass has wide applications in optics, optoelectronics and phase change memories [1]. The structure of this glass is still not well understood. Elucidation of a structure might help in the development of this material. The AgAsS2 glass was prepared by the melt-quenched technique. The product was characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive x-ray (EDX) spectroscopy. The clusters generated during laser desorption ionization (LDI) of AgAsS2 glass were identified by a quadrupole ion trap time-of-flight mass spectrometer (QIT-TOFMS). The formation of singly charged 3 unary (Ag+/- and As3+), 38 binary (AsnSx, AgmSx) and 98 ternary (AgmAsnSx) clusters was proved. Silver rich nano-grains are formed during AgAsS2 glass synthesis. These nano-grains have been identified using TEM analysis and verified also by QIT TOF mass spectrometry. The results show that the structure of AgAsS2 glass is “nanograin-like” where grains are either 1.
