Особенности спектров фотолюминесценции монокристаллического оксида алюминия

Abstract

The results of the luminescence studies of aluminum oxide are presented. Excitation and emission spectra are measured. It is shown that the excitation spectrum has peaks equal to 205 (F), 210 (Ti4+) and 220 (F+) nm, which correspond to the intrinsic and impurity centers of excitation, and emission spectrum has peaks 410 (F) and 795 (F) nm. It is revealed that the excitation and emission bands of A120 3 single crystal conform to the theoretically expected.
