“…16, curve 1) is typical for Ni(II) ions in silicate and aluminosilicate glasses with high silica content [108] and references therein]. After heattreatment, the initial brown colored glass takes on a green color, the absorption spectrum typical of nickel-containing aluminomagnesium spinel [109] appears (Fig.…”

“…So it is quite natural to try to develop thermal shock resistant optical filters based on glass-ceramics of LAS system. A systematic study of NiO-doped glasses of the lithium aluminosilicate system indicate that as a result of secondary heattreatments, Ni(II) ions enter aluminotitanate amorphous regions (660-700°C); form Ni 2 AlO 4 spinel phase (720-780°C); and enter β-quartz ss (800-900°C) [108]. Ni(II) ions in nanocrystals of spinel ss (NiAl 2 O 4 -γ-Al 2 O 3 ) produce different tints of green color depending on the composition of the initial glass and heat-treatment conditions.…”

“…Ni(II) ions in nanocrystals of spinel ss (NiAl 2 O 4 -γ-Al 2 O 3 ) produce different tints of green color depending on the composition of the initial glass and heat-treatment conditions. "Low-temperature" prolonged heat-treatments lead to crystallization of β-quarts ss without decomposition of spinel crystals and to the preparation of green LAS glass-ceramics with defined color coordinates and low coefficient on thermal expansion (CTE) [110,111]. When Ni(II) ions enter β-quartz ss, the color of glass-ceramics changes to purple and red.…”

“…When Ni(II) ions enter β-quartz ss, the color of glass-ceramics changes to purple and red. This was used in the development of LAS glass-ceramics with near zero CTE for thermal shock resistant purple and red color filters [110][111][112]. We developed also transparent blue, gray, and violet glass-ceramics for thermal shock resistant color filters.…”

A series of glass samples were prepared from a mixtures of B2Oa, Na20 and NiO. The role of nickel oxide in a glass matrix was studied by using infrared spectra, optical absorption, magnetic susceptibility, density, and differential thermal analysis (DTA). It was shown that the addition of nickel oxide at different concentrations to the glass batches causes some deformation in the glass structure. The values of ligand field strength and Racah parameter indicated an increasing degree of covalency. The glass samples exhibited diamagnetic behaviour with NiO content up to 1 g, then paramagnetic behaviour. The densities and glass transition temperatures decreased with increase in the NiO content up to 0.2 g and then increased again. This tendency may be related to changes in the glass structure.

Donor–Acceptor Control in Grown‐in‐Glass Gallium Oxide Nanocrystals by Crystallization‐driven Heterovalent Doping

Incorporation of doping ions in nanocrystals is a strategy for providing nanophases with functions directly related to ion features. At the nanoscale, however, doping can also activate more complex effects mediated by perturbation of the nanophase size and structure. Here, we report a paradigmatic case in which we modify grown-in-glass γ-Ga O nanophases by nickel or titanium doping of the starting glass, so as to control the concentration of oxygen and gallium vacancies responsible for the light emission. Optical absorption and luminescence show that Ni and Ti ions enter into the nanophase, but differential scanning calorimetry and X-ray diffraction indicate that Ni and Ti also work as modifiers of nanocrystal growth. As a result, doping influences nanocrystal size and concentration, which in turn dictate the number of donors and acceptors per nanocrystal. Finally, the chain of effects turns out to control both the intensity and spectral distribution of the light emission.
