“…Interpretation of the radiative energy transfer was already published [1,23,28,29]. This higher Yb 3+ concentration limit for the increase of the decay time in fluorides is apparently due to a weaker non-radiative energy transfer effect or self-quenching than in oxides because of their lower phonon energy.…”

“…8), one can see that many resonant and non-resonant energy transfer are possible between trivalent RE ions. Indeed, energy transfers between Yb 3+ and Er 3+ or Tm 3+ are well known [29,31]. Especially in the 10.000 cm −1 energy range, matching with excited state of Yb 3+ , energy transfers are allowed with the different excited levels of Er 3+ and Tm 3+ ions giving rise to several peaks in the visible as it is clearly seen in Fig.…”

Optical properties of erbium ions in MBE-grown GaN-thin films are reported. Three types of sites were identified using site selective laser excitation. The main center is ascribed to the Er 3+ ions substituted in the Ga sub-lattice while the two other centers are assigned to Er-related defects. The lifetimes of the 4 S 3/2 and 4 I 13/2 multiplets of the main center are strongly quenched with increasing Er concentration. The complex decay profile of the visible fluorescence and its concentration dependence were modeled and interpreted using the diffusion-limited model.The dynamics of the infrared emission at 1.54 m from the 4 I 13/2 multiplet after excitation in the visible range is discussed. The crystal field strength of Er 3+ in GaN was deduced from the overall crystal field splitting of the ground multiplet. Comparison of the results with those obtained in inorganic materials indicates that the rare earth is well embedded in the semiconductor host and not in a impurity oxide phase.

Abstract-Solar pumped laser (SPL) can find wide applications in space missions, especially for long lasting ones. In this paper a new technological approach for the realization of a SPL based on fiber laser technology is proposed. We present a preliminary study, focused on the active material performance evaluation, towards the realization of a Nd 3+ -doped fiber laser made of phosphate glass materials, emitting at 1.06 μm. For this research several Nd 3+ -doped phosphate glass samples were fabricated, with concentration of Nd 3+ up to 10 mol%. Physical and thermal properties of the glasses were measured and their spectroscopic properties are described. The effect of Nd 3+ doping concentration on emission spectra and lifetimes was investigated in order to study the concentration quenching effect on luminescence performance.
