“…The luminescence shape of 15% of the ZnF2 sample under 796 nm excitation is missing because of the weak signal level caused by the sample being opaque and too low signal of the laser pump. Usually, the low thermal stability of glass leads to a fast crystallization process [1,5], losing transparency. In our case, the samples annealed at Tx (THL) temperature kept their transparent character.…”

“…Oxy-fluoride glasses and glass-ceramic are promising fields of research because of their possibility of creating new types of glasses with unique parameters. Oxy-fluoride glasses combine low phonon-energy [1], improved radiative emission, and luminescence shaping from fluoride glasses with the mechanical and thermal stability usually found in oxide glasses [2]. Broadband light sources are desired in various fields like medicine, sensors, and optical amplifiers [3][4].…”

New broadband-emitting materials are still in demand for industrial, medical, and telecommunications solutions. Thus, new materials that improve the luminescence of lanthanide ions are in demand. Equally important seems to be the co-doping of the host material with different lanthanides, for example Er3+ and Tm3+. In co-doped materials, energy transfers between ions depend on lanthanide ions concentrations, host material chemical composition and structure. To improve the efficiency of energy transfer and radiative transitions, low-phonon matrices should be used. One of various solutions is the use of oxide-fluoride matrices, where the oxide part of the matrix provides the desired thermal and mechanical stability and the fluoride part provides a low-phonon environment for the ions. In this report, influence of concentration of ZnF2 on the co-doped oxide matrix was investigated in terms of luminescence changes. Full Text: PDF References J.
