This paper presents the results of a study of the pulsed cathodoluminescence of samples of neodymium-doped yttrium aluminates. It is found that the <i>d</i>–<i>f</i> emission bands of the Nd<sup>3+</sup> ion dominate the spectrum of yttrium aluminum garnet in the visible region. The relative intensities and widths of the <i>d</i>–<i>f</i> bands vary as the crystal structure changes, and new luminescence bands appear. The luminescence bands of Nd<sup>3+</sup> in the yttrium aluminum garnet and orthorhombic yttrium monoaluminate structures are identified. It is proposed to use two regions of the emission bands of Nd<sup>3+</sup> in yttrium aluminum garnet as analytical bands to determine the concentration of the cubic phase: those at λ<sub>1</sub>=350–500 nm and λ<sub>2</sub>=501–650 nm.
