Energy Structure of Emission Centers in Solutions with Silver Impurity

The spectral properties of solutions of oxygen-containing salts and acids with admixture of Аg+ ions were studied. The spectra of absorption, photoluminescence, and photoluminescence excitation for such systems are measured in the temperature range of 4.2–290 K. The energy structure of absorption and emission centers in the solution was determined. It is shown that the spectra under study are caused by the electron transitions between the energy levels, whose structure is deformed as a result of the interaction of ions Ag+ with the environment. The experimental results are interpreted on the basis of an ionic model for complexes for investigated solutions.
