В работе приведены результаты исследований зависимости люминесцентных свойств образцов керамики от их положения в тигле при облучении. Для синтеза готовилась шихта из смеси порошков окислов оксида алюминия, оксида иттрия. Соотношение окислов в шихте соответствовало стехиометрическому. Частицы порошков окислов имели размеры около 1мкм и меньше. Синтез осуществлялся на ускорителе электронов Института ядерной физики СО РАН (г. Новосибирск). Люминесцентные свойства были измерены на спектрофлуориметре СМ 2203 производства «СОЛАР» при возбуждении монохроматическим излучением на 450 нм. Исследованы двавида образцов, отличающиеся величиной насыпной плотности и предысторией оксида иттрия.
