“…For the samples synthesis a sodium-boron matrix was used, since it proved to be the most promising for the synthesis of glass ceramics with YNbO 4 [5]. The sodium-boron matrix is characterized by a relatively low synthesis temperature under standard conditions (from 900 • C).…”

“…3, b and 4, b) there are bands associated with energy transitions Tb 3+ from levels 5 D 3 − 7 F J (J = 6, 5, 4) and 5 D 4 − 7 F J (J = 6, 5, 4, 3, 2, 1, 0), while transitions from 5 D 3 levels have an extremely low CL intensity and are noticeable only on semilogarithmic scale. The shape of the spectrum corresponds to the spectrum of Tb 3+ in YNbO 4 [10,11], where REIs replace Y ions with a local position C 2 [5].…”

“…In the papers [3,4] the possibility of high-temperature synthesis of glass-ceramic materials with yttrium niobate crystallites was shown. In the course of previous studies [5,6] it was found that the boron-sodium oxide matrix is extremely promising for the low-temperature synthesis of REI-doped yttrium niobate.…”

The main aim of this work was to perform low-temperature synthesis of glass-ceramics with YNbO4 : Tb3+ crystalline inclusions and study the structural and luminescent properties of the samples synthesized. In the framework of this work, inclusions crystallized in the system B2O5-Na2O-Y2O3 -Nb2O5-Tb4O7 (Bura). It was shown that in this system, regardless of the precursors in the samples, YNbO4 : Tb3+ in an amount of more than 70% of the total crystalline component. The most promising system for the synthesis of activated glass-ceramics with YNbO4 proved to be synthesized from oxide precursors; it crystallized more than 95% YNbO4 : Tb3+ of the total crystalline component. The luminescent properties of crystalline inclusions were studied using the local cathodoluminescence method. The composition and structure of glass ceramics were studied by methods X-ray spectral microanalysis and X-ray diffraction phase analysis. Keywords: YNbO4 : Tb3+, luminescence, glass-ceramics.

“…For the synthesis of glass ceramics, a sodium-boron matrix was chosen, since it proved to be the most promising for the synthesis of glass ceramics with YNbO 4 [3,4]. Yttrium, niobium, and terbium compounds were added to the matrix in such a proportion that the following molar ratios in terms of oxides were met in the synthesized material: M(…”

“…Their synthesis and subsequent treatment are similar to the synthesis and treatment of glass, while the level of nonradiative losses during luminescence excitation are much lower than in all-amorphous materials. In the course of previous studies [3][4][5] it was found that the boron sodium oxide matrix is extremely promising for the lowtemperature synthesis of REI-doped yttrium niobate.…”

The optimal temperature regime for the synthesis of glass ceramics with YNbO4 : Tb3+ crystalline inclusions has been established. Glass ceramics were synthesized on the basis of a sodium borate matrix from oxide precursors. It has been established that synthesis at a temperature of 950oC is optimal, since at this temperature only one crystalline phase YNbO4 : Tb3+ is formed in the glass and its content is maximum. The spectra of crystalline inclusions and the glass matrix were obtained by the method of local cathodoluminescence, the phase composition of glass ceramics was studied by X-ray phase analysis. Keywords: YNbO4, luminescence, terbium ion, glass ceramics.
