Optical properties of chalcogenide glasses with ion-synthesized copper nanoparticles

On the energetic criterion for destructive clustering of metallic nanoparticles in chalcogenide and oxide glassy matrices

“…In contrast to our analysis, the principal possibility to agglomerate implanted Cu NPs in As 2 S 3 and Ge 15.8 As 21 S 63.2 ChGs in full analogy to silica SiO 2 glass was declared in Ref. . It was asserted that these NPs can be also gathered in spherical entities of 5–10 nm radius, giving essential changes in linear optical absorption at ∼580–590 nm and nonlinear properties reflected in Z‐scan measurements.…”

“…optical transmission spectra for different ChGs of the As–S system, showing that only S‐rich glasses transmit incident light near ∼500–520 nm, but at evidently higher saturation (with respect to the Fresnel's formula , the 69% transmission corresponds to n ≅ 2.5). It was also strange why implantation in arranged at such high dose (10 17 ions cm −2 ) did not change optical transmission of implanted samples giving point‐to‐point coincidence with data for pristine glass in the full spectral range excepting 580–590 nm (Fig. ).…”

“…, this LSPR band positioned due to spherical NPs formalism is expected in ChGs ( n > 2.5) at longer wavelengths (above 620–630 nm). Secondly, the Z‐scan measurements (imagined in as full evidence of enhanced optical nonlinearities) was performed only for implanted ChGs, but not compared with pristine nonimplanted ones. Thirdly, it seems doubtful to accept that the optical transmission spectrum in can be ascribed to As 2 S 3 glass of 1 mm thickness.…”
