- Abstract
We have ground bulk samples to obtain nanoparticles of (GaS)(EuO) solid solutions, the sizes of which were determined using an atomic force microscope. The photoluminescence spectra of the nanoparticles were studied in the temperature interval 77-300 K. We have established the mechanisms for emission and transfer of energy from the matrix to the rare-earth ion, and we determined the Stokes shift (ΔS = 0.7 eV), the Huang-Rhys parameter ( S = 16), and the optical phonon energy (ħ−ω = 23 meV).
