Paper Abstract

It is shown that short-wave emission of Tb3+ may be using as an optical indicator of thin film electroluminescent structures matrix changes because that emission shows a high spectral response to the crystal field symmetry change near Tb3+ ion. Depending on the conditions of preparation of the film, the annealing temperature, the action of the gamma-ray radiation of the Tb3+ electroluminescent spectra's view corroborates the conclusion. Electroluminescent long-wave part spectra compared with short-wave part spectra at T equals 4.2 divided by 300 K regarding the dependence on film preparation conditions. Such comparisons demonstrate an advantage of using over `green' emission of `violet' emission terbium as an optical indicator.
