Abstract
Epitaxial films of composition (Gd,Nd)3Ga5O12 or (Gd,Y,Nd)3Ga5O12 with a neodymium content varying from 0.3 to 15 at. % are grown by liquid-phase epitaxy from a supercooled PbO-B2O3-based solution melt on Gd3Ga5O12(111) substrates. The optical absorption spectra of the epitaxial films grown are measured in the wavelength range 0.2–1.0 µm. The results of interpreting the absorption bands observed in the spectra are used to construct the energy level diagrams of Nd3+ and Gd3+ ions in the matrices of the epitaxial films.
