Redrawn Phase-Separated Borosilicate Glasses: A TEM Investigation

Influence of ultraviolet irradiation and heat treatment on the morphology of silver nanoparticles in photothermorefractive glasses

“…For example, silver nanoparticles in borosilicate glasses can have the shape of an oblong ellipsoid [15,16]. The examination of the electron microscope images of silver nanoparticles in the phosphate glasses studied in [15,17] has revealed that the nanoparticles in these glasses also…”

“…Under the assumption that ellipsoids in the medium are oriented randomly, the averaged absorption cross section of the ellipsoid can be represented in the form (7) Reasoning from the data presented in [15][16][17], we can restrict our consideration to the particular case of an oblong ellipsoid: a > b, c. Without a loss in generality, we can assume that the ellipsoid has a symmetry along the longer axis: a > b = c (see the inset to Fig. 4).…”

Quantitative AFM analysis of phase separated borosilicate glass surfaces

“…The development of phase separation in glasses has been intensively studied experimentally in the last decades [12]. Various techniques have been used to follow this phenomenon: visible or X scattering [13][14][15][16][17], electronic microscopy [18,19], infrared or Raman spectroscopy [20][21][22][23]. Most of the times, these techniques are used to test the occurrence of phase separation and to describe its morphology (droplet or interconnected).…”

The polarization properties of a tilted polarizer

“…Close to grazing incidence θ → 90 • , the latter deviates, which we can understand in a physical picture. The particles embedded in our polarizer are cigar-shaped [23,24]. Relevant for the polarization effect is the coupling of the light field to their long axes P P P A .…”
