Correlation between dopant content and excited-state dynamics properties in Er3+–Yb3+-codoped Y2O3 by using a new combinatorial method

Why so deep research on Yb3+-doped optical inorganic materials?

“…These methods allow the development of characterization of optical parameters in solid-state samples, and also the growth of flexible single crystal laser fibres which might be mainly used as high average power solid-state lasers under high-power laser diode. We have chosen to study Y 3 Al 5 O 12 (YAG) yttrium aluminium garnet [13][14][15][16], Gd 3 Ga 5 O 12 (GGG) gadolinium gallium garnet [17,18], Y 2 O 3 yttria sesquioxide [14][15][16][17][18][19][20] and CaF 2 [21] fluoride as typical examples of Yb 3+ -doped hosts, which are considered among important laser crystals due to their unusual combination of favourable properties. The room temperature absorption and emission of spectra of Yb 3+ -doped YAG crystals, which were grown by LHPG technique, are shown in Fig.…”

Rare Earth Compound Nanotubes

“…This coincides well with the down conversion emission (two bands, 500 nm and 730 nm) of these nanotubes when excited with 300, 310, or 320 nm Xe light sources. [10] The excellent luminescent properties of these functionalized nanotubes may find applications such as biological labels [11±14] or optoelectronic and nanodevices.…”

Advances in growth of fiber crystal by the LHPG technique. Application to the optimization of Yb3+-doped CaF2 laser crystals

“…3 show clearly many more lines than can be expected for an electronic transition alone. The observation is the same in Y 2 O 3 sesquioxide [7][8][9] and YAG garnet [10][11][12][13]. The reason is the strong electron-phonon coupling giving rise to both electronic and vibronic transitions.…”

“…2b shows the ytterbium concentration gradient between 0% and 15% obtained in Yb 3+ -doped CaF 2 crystalline fiber (pulling rate: 30 mm/h). This ''combinatorial chemistry method'' has been successfully applied to the study of Yb 3+ -Er 3+ co-doped and Yb 3+ mono-doped sesquioxides [7][8][9] and YAG [10][11][12][13].…”
