Broadening and enhancing 2.7 μm emission spectra in Er/Ho co-doped oxyfluoride germanosilicate glass ceramics by imparting multiple local structures to rare earth ions
TL;DR: Er/Ho co-doped oxyfluoride germanosilicate glass and glass ceramics are prepared and compared in this paper, and the results indicate that the glass consists of SiO4 and GeO4 structural units.
Journal ArticleDOI
Mid-infrared fluorescence properties, structure and energy transfer around 2 µm in Tm 3+ /Ho 3+ co-doped tellurite glass
TL;DR: Tm 3+ /Ho 3+ doped tellurite glasses with good thermal stability and low phonon energy are prepared in this paper, where the energy transfer mechanism between Tm 3 + and Ho 3+ has been analyzed according to the absorption spectra, the emission spectra and the level structures of Tm+ and Ho3+ ions.
Journal ArticleDOI
Comprehensive studies of the Ag+ effect on borosilicate glass ceramics containing Ag nanoparticles and Er-doped hexagonal NaYF4 nanocrystals: morphology, structure, and 2.7 μm emission
TL;DR: In this paper, the effect of Ag+ ions on the glass forming and crystallization processes was discussed in detail by glass structural analysis, and it was found that the Ag+ concentration can affect the distribution of Na+ ion and bridge oxygen in boron-rich and silicon-rich phases, which induced the transformation between BO3 triangles and BO4 tetrahedra during crystallization process.
