“…2. The emission bands observed in the spectra were deciphered from the literature [8,11,[17][18][19]. The spectrum of the 1-Eu sample exhibited bands associated with transitions from the 5 D 0 Eu 3+ levels to the 7 F 1,2,3 and the transition band 5 D 1 − 7 F 2 .…”

“…In some cases, an analysis of the shape of the emitted spectrum of Eu 3+ makes it possible to estimate the local environment of this ion and, consequently, the symmetry of the matrix in which it is included [10]. Nevertheless, such an activator in the f −ZrO 2 matrix has a rather low luminescence intensity [11]. The phenomenon of sensitization can be used to increase this intensity.…”

In this work, stabilized f-ZrO2 ceramic samples with the compositions of (Zr0.82Y0.09Eu0.09)O1.91, (Zr0.82Y0.09Tb0.09)O1.91 and (Zr0.82Y0.09Eu0.045Tb0.045)O1.91 were studied. The elemental composition was studied by electron probe microanalysis, and the luminescent properties were studied by local cathodoluminescence (CL). An analysis of the Eu3+ CL spectra confirmed the stabilization of the cubic phase in ceramics at room temperature. The study of the obtained CL spectra, the 5D4-7F5Tb3+ band luminescence decay kinetics, CL images and excitation spectra showed europium sensitization by terbium in (Zr0.82Y0.09Eu0.045Tb0.045)O1.91.

“…В некоторых случаях анализ формы спектра излучения Eu3+ позволяет судить об локальном окружении этого иона и, следовательно, о симметрии матрицы, в которую он внесен [10]. Тем не менее такой активатор в матрице f −ZrO 2 имеет достаточно низкую интенсивность люминесценции [11]. Для увеличения этой интенсивности можно использовать явление сенсибилизации.…”

“…2. Наблюдаемые на спектрах полосы излучения были расшифрованы по литературным данным[8,11,[17][18][19]. В спектре образца 1-Eu наблюдались полосы, связанные с переходами с уровней 5 D 0 Eu 3+ на уровни7 F 1,2,3 и полоса перехода 5 D 1− Для образца 2-Tb проявились линии, относящееся к переходам с уровня 5 D 4 Tb 3+ на уровни 7 F 3,4,5,6 .…”

“…Спектральное положение, соотношение интенсивностей полос и количество расщеплений в спектрах редкоземельных ионов зависят от локальной симметрии иона в материале. Благодаря этому Eu 3+ можно использовать в качестве люминесцентного зонда, по спектрам которого можно идентифицировать локальное окружение РЗИ в легированном материале [12,13].…”

The main purpose of this work was to carry out a low-temperature synthesis of glass ceramics containing YNbO4:Eu3+ crystallites and to study the structural and luminescent properties of the obtained samples. Within the framework of this work, the inclusions that crystallized under the conditions of low-temperature synthesis in the systems of SiO2-Na2O-K2O-Y2O3-Nb2O5-Eu2O3 (SiNaK) and B2O5-Na2O-Y2O3-Nb2O5-Eu2O3 (BNa) were investigated for the first time. It was shown that YNbO4: Eu3+ crystallized in both considered systems. In the SiNaK system the crystallization of SiO2 also occurred (quartz, crisstabolite, and tridymite) under the selected conditions. The BNa system proved to be the most promising for the synthesis of activated glass-ceramics with YNbO4, since the required crystallites crystallized only in ithis system. The luminescent properties of crystalline inclusions were investigated using the local cathodoluminescence technique. The composition and structure of glass ceramics were studied by electron-probe microanalysis and X-ray diffraction phase analysis.
