“…В ряде работ продемонстрирована возможность записи оптической информации в стеклах путем создания или трансформации некоторых ансамблей, имеющих отличную от матрицы стекла люминесценцию. Такими ансамблями могут являться нейтральные или заряженные молекулярные кластеры серебра, которые обладают интенсивной люминесценцией в видимой области спектра [18][19][20]. Так, в работе [18] была показана возможность записи оптической информации в серебросодержащих фототерморефрактивных стеклах путем создания люминесцентных центров УФ излучением.…”

The results of complex X-ray and ultraviolet (UV) nanosecond laser radiations action on alkali-containing silicate glasses is presented.It is shown that under the action of X-ray radiation color centers with luminescent properties appear in glasses. This is caused by the increase of concentration of glass network structural defects. Under the action of laser radiation the destruction of these defects takes place, accompanied by the bleaching of glass and by the disappearance of luminescence. The dynamic of glass bleaching under the laser action and the influence of alkali metals ions (Li, Na, K) on this precess is studied. The mechanisms of color centers destruction by laser radiation are proposed..

Glass‐ceramics (GC) generally possess enhanced mechanical properties compared to their parent glasses. The knowledge of how crystallization evolves and affects the mechanical properties with increasing temperature is essential to optimize the design of the crystallization cycle. In this study, we crystallized a glass of the MgO–Al2O3–SiO2 system with nucleating agents TiO2 and ZrO2. The crystallization cycle comprised a 48 hour nucleation treatment at the glass‐transition temperature followed by a 10 hour growth step at a higher temperature. During this cycle, the evolution of crystalline phases was followed by high‐temperature X‐ray diffraction (HTXRD), which revealed the presence of karooite (MgO·2TiO2), spinel (MgO·Al2O3), rutile (TiO2), sillimanite (Al2O3·SiO2), and sapphirine (4MgO·5Al2O3·2SiO2). The same heat treatment was applied for in situ measurement of elastic properties: elastic modulus, E, shear modulus, G, and Poisson's ratio, ν. The evolution of these parameters during the heating path from room temperature to the final crystallization temperature and during the nucleation and the crystallization plateaus is discussed. E and G evolve significantly in the first two hours of the growth step. At the end of the crystallization process, the elastic and shear moduli of the GC were approximately 20% larger than those of the parent glass.

“…Silver clusters, which are subnanosized aggregates consisting of several silver atoms and/or ions, in glasses are well known (Bourhis et al 2013;Dubrovin et al 2014) to have an intense broadband luminescence in the visible. Today glasses with luminescent silver clusters were proposed to be used as phosphors for white LEDs (A. S. Kuznetsov et al 2013), luminescence down-shifting cover glasses for solar cells (Cattaruzza et al 2015), and optical data storage media (Klyukin et al 2014). However, low quantum efficiency of luminescence of silver clusters stabilized in various glass hosts, which does not exceed 35% at room temperature up to now (Sgibnev et al 2016;Cattaruzza et al 2015;Kuznetsov et al 2012), limits their industrial applications.…”

Photo-thermo-refractive glasses are now attractive material for developing various elements and devices of photonics. Influence of antimony oxide content in the photo-thermo-refractive glass composition and subsequent heat treatment temperature on the spectral-luminescent properties of silver non-metal clusters and metal nanoparticles formed with low-temperature ion exchange method were studied. Silver clusters in ion-exchanged Sb-doped photo-thermo-refractive glasses reveal broadband and intense emission in the visible and near infrared ranges. Absolute quantum yield of luminescence reaches 63% (λex=365 nm), which opens up new prospects for using such materials as phosphors for white LEDs and down-convertors for solar cells.
