This paper presents the results of a study of the pulsed cathodoluminescence of samples of neodymium-doped yttrium aluminates. It is found that the d–f emission bands of the Nd3+ ion dominate the spectrum of yttrium aluminum garnet in the visible region. The relative intensities and widths of the d–f bands vary as the crystal structure changes, and new luminescence bands appear. The luminescence bands of Nd3+ in the yttrium aluminum garnet and orthorhombic yttrium monoaluminate structures are identified. It is proposed to use two regions of the emission bands of Nd3+ in yttrium aluminum garnet as analytical bands to determine the concentration of the cubic phase: those at λ1=350–500 nm and λ2=501–650 nm.
