Identification of Luminescence Bands of Nd[sup 3+] Ions in Yttrium Aluminates Y[sub 3]Al[sub 5]O[sub 12] and YAlO[sub 3

Abstract

The pulsed cathodoluminescence spectra of yttrium aluminum garnet and perovskite activated by neodymium are investigated at room temperature in the wavelength range 250–750 nm. The luminescence bands are identified, and all of them are assigned to Nd3+ transitions, including those from the doublet levels.
