Жұмыста керамикалық үлгілердің люминесцентті қасиеттерінің сәулелендіру кезіндегі тигельдегі орналасуына тәуелділігін зерттеу нәтижелері берілген. Синтез үшін химиялық таза сортты Al2O3, Y2O3, Gd2O3 және Ce2O3 тотықтарының қоспаларынан үлгі дайындалды. Зарядтағы оксидтердің қатынасы стехиометриялық қатынасқа сәйкес келді. Оксид ұнтақтарының бөлшектерінің мөлшері шамамен 1 мкм немесе одан аз болды. Синтез РҒФ СБ Ядролық физика институтында (Новосибирск қ.) электрондар үдеткішінде жүргізілді. Люминесцентті қасиеттер 450 нм монохроматикалық сәулелену арқылы SOLAR шығарған CM 2203 спектрофлориметрінде өлшенді. Үлгілердің екі түрі зерттелді, олар массалық тығыздығы мен итрий оксидінің тарихымен ерекшеленді.
