Pre-crystallization heat treatment and infrared luminescence enhancement in ni2-doped transparent glass-ceramics / N. V. Golubev, E. S. Ignat'eva, V. M. Mashinsky et al. // Journal of Non-Crystalline Solids. — 2019. — Vol. 515. — P. 42–49. We report on design and fabrication of Ni2+-doped glass-ceramics from a low-alkali optical glass in Li2O-Na2O-Ga2O3-SiO2-GeO2 system by melting technique and subsequent thermally controlled nano-crystallization. The analysis of differential scanning calorimetry, X-ray diffraction, transmission electron microscopy, absorption and fluorescence spectroscopy reveals, for the first time, the real possibility of optimizing the integrated intensity of Ni2+ near-infrared emission through controlled pre-treatments at temperatures of nanophase nucleation, with the enhancement up to a factor of four with respect to gallium germanosilicate glass-ceramics obtained without pre-treatments. Importantly, the effects on the light emission are shown to be related to the influence of pre-treatment on size and size distribution of the gallium oxide nanocrystals which result from subsequent crystallization at higher temperature.

Responsive charge transport in wide-band-gap oxide films of nanostructured amorphous alkali-gallium-germanosilicate / J. Remondina, A. Paleari, N. V. Golubev et al. // Journal of Materials Chemistry С. — 2019.

Direct femtosecond laser-induced formation of cds quantum dots inside silicate glass / M. P. Vetchinnikov, A. S. Lipatiev, G. Y. Shakhgildyan et al. // Optics Letters. — 2018. — Vol. 43, no. 11. — P. 2519–2522. We report the one-step precipitation of CdS quantum dots in the volume of CdS-doped silicate glass under the focused femtosecond laser beam without additional heat treatment of glass. Femtosecond direct laser writing leads to the annular distribution of the precipitated CdS quantum dots in laser-written domain optical properties of which could be tuned by laser beam parameters. Increasing the laser pulse number to 103 significantly enhances luminescence intensity in the domains, while further increasing up to 106 pulses leads to luminescence quenching. A possible scenario for the formation and distribution of quantum dots is proposed. [ DOI ]

One-step micro-modification of optical properties in silver-doped zinc phosphate glasses by femtosecond direct laser writing / G. Y. Shakhgildyan, A. S. Lipatiev, M. P. Vetchinnikov et al. // Journal of Non-Crystalline Solids. — 2018. — Vol. 481. — P. 634–642. We demonstrate the possibility of joint formation of fluorescent silver clusters and plasmonic silver nanoparticles spatially confined in micron-sized domains by the one-step femtosecond direct laser writing (DLW) without subsequent heat treatment in zinc phosphate glasses with different concentration of silver. We show that DLW in glass induces local micro-modification of optical properties resulted in the appearance of luminescence, absorption and form birefringence in domains. Variation of laser pulse energy allows controlling the micro-modification process and tuning of optical properties. We propose a possible mechanism for observed phenomena that includes local chemical redistribution of glass network modifiers during DLW process. We believe that ability to form complex 3D shapes of luminescent, plasmonic and birefringent structures embedded in dielectric transparent glass materials opens new routes for the design of nanophotonic devices and multidimensional optical memory.
