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 Nd~(3+) 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 Nd~(3+) 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~(3+) in yttrium aluminum garnet as analytical bands to determine the concentration of the cubic phase: those at _1 D 350-500 nm and _2 D 501-650 nm.
