Исследованы структура и люминесцентные свойства люминофора Sr3Y2Ge3O12, активированного Eu3+ (SYGO:Eu3+), синтезированного золь-гель методом при 1200°С в течение 8 ч, оптимальная концентрация допирования 5 мол.% Eu3+. При возбуждении в ближнем УФ-диапазоне при 395 нм люминофоры SYGO:x мол.% Eu3+ показали красное излучение Eu3+ (5D0–7F1) при 612 нм, интенсивность фотолюминесценции максимальна для 5 мол.% Eu3+. Рентгеноструктурный анализ материалов SYGO демонстрирует однофазную структуру, принадлежащую пространственной группе Ia3d (230). Показано, что ион Eu3+ замещает асимметричное положение в SYGO, в частности положение Sr2+, путем расчета ионного радиуса. Исследуемые красные люминофоры обладают высокой интенсивностью люминесценции и темно-красным излучением и могут применяться в качестве материалов с красным люминофором в белых светодиодах при возбуждении в ближнем УФ-диапазоне.

This paper is aimed at investigating the structure and luminescence properties of Sr3Y2Ge3O12 activated by Eu3+ (SYGO:Eu3+), which were synthesized by using the sol-gel method. The synthesis was conducted at 1200°C for 8 h, with an optimal doping concentration of 5 mol% Eu3+. Under near-ultraviolet excitations at 395 nm, SYGO:x mol.% Eu3+ phosphors showed the red emission of Eu3+ (5D0–7F1) at 612 nm, and the photoluminescence intensity was highest at 5 mol.% Eu3+ doping. X-ray diffraction analysis of SYGO materials displays a single-phase structure that belongs to the Ia3d (230) space group. The result showed that the Eu3+ ion substitutes the asymmetrical location in the SYGO host, particularly the Sr2+ position, by calculating the ionic radius. In addition, the investigated red phosphors show high luminescence intensity and deep red emission. Thus, they show application potential as red-emitting phosphor materials in white LEDs under near-ultraviolet excitations.
