Введение. В работе исследованы структурные и люминесцентные свойства нанокристаллических порошков состава Y3Al5O12:Re3+ (Re3+ = Nd3+, Yb3+, Ce3+), синтезированных модифицированным методом Печини с использованием поливинилпирролидона в качестве дополнительного стабилизатора и органического «топлива» в ходе синтеза. Метод. Для исследования термической эволюции гелей и свойств конечного продукта применены фурье-спектроскопия, люминесцентная спектроскопия, дифференциальная сканирующая калориметрия, сканирующая электронная микроскопия, а также рентгенофазовый анализ. Основные результаты. Показано, что применение модифицированного метода Печини при использовании добавок поливинилпирролидона в исходные растворы обеспечивает получение высокодисперсных порошков алюмоиттриевого граната, содержащих редкоземельные ионы. Установлено, что введение поливинилпирролидона оказывает существенное влияние на эволюцию композиционных гелей при их термообработке и формирование нанокристаллов алюмоиттриевого граната происходит при температуре около 883 °С. Обсуждение. Полученные в работе нанокристаллические порошки могут быть использованы в качестве прекурсоров для спекания лазерной керамики и введены в оптическое волокно для создания усилителей.

Synthesis of nanocrystalline yttrium-aluminum garnet doped with neodymium was performed via modified Pechini methods. Evolution of material during synthesis was studied using differential thermal analysis; the structure and morphology of synthesized nanopowders were studied using scanning electron microscopy and x-ray diffraction. It was shown that the use of an additional low-temperature stabilizer leads to formation of crystalline yttrium-aluminum garnet phase at lower temperatures. It was shown that the formation of nanocrystals occurs at the temperature of about 883 °C. Obtained powders can be used as precursors for ceramics sintering or be introduced into the optical fiber in order to fabricate optical amplifiers.
