Abstract. We show that the degree of linear polarization of the photoluminescence of tris-(8-hydroxyquinoline)aluminium (Alq3) thin film can be increased by about 10 times, using a method of oblique-angle deposition. This is due to greater ordering of molecular alignment in this thin film.

Keywords: tris-(8-hydroxyquionoline)aluminium, photoluminescence, polarization, oblique-angle deposition, thin films

Анотація. Показано, що ступінь лінійної поляризації фотолюмінесценції тонкої плівки три-(8-гідроксихінолін)алюмінію (Alq3) можна збільшити приблизно в 10 разів, використовуючи метод осадження під деяким кутом до нормалі. Це пов’язано з більшим упорядкуванням молекулярного вирівнювання в цій тонкій плівці.

Ключові слова: тріс(8-гідроксихінолінат)алюміній, фотолюмінесценція, поляризація, косокутове осадження, тонкі плівки
