Study of the fabrication parameters of large core Yb2O3 doped optical fibre through solution doping technique

Catalytic performance of porous Yb2O3 sesquioxide

“…Ytterbia (Yb 2 O 3 ) is a rare earth oxide, which is of significant interest to sensor and laser technologies [1][2][3][4][5][6][7], and as an aid for sintering and doping of different ceramics [8][9][10], as well as numerous catalytic applications [11][12][13][14][15][16][17]. One of the applications included Yb 2 O 3 being used as selective emitters in high-temperature sensors due to its ability to emit radiation selectively in the infrared region when returning to the ground state after being heated up [6].…”

“…Unlike Nd, which is also used for doping of amorphous materials, Yb electronic structure allows avoiding most of the parasitic effects, such as upconversion, cross relaxation, or excited-state absorption, which are important to avoid in applications of high energy lasers [2]. Silica is one of the materials used for optical fibres; however, Yb 2 O 3 doping for silica glasses is limited to 1-2 wt-%, which is not optimal for use in small laser devices [3,4]. However, the study of the optical properties of the Yb 2 O 3 doped tellurite glasses (TeO 2 -GeO 2 -K 2 O) demonstrated an increase in this glass's refractive index with the increase in the Yb 2 O 3 content [5].…”

Semiconductor nanomaterials for environmental applications

“…Among various lanthanide oxide nanomaterials, the ytterbium oxide (Yb2O3) is considered as an important C-type cubic refractory sesquioxide due to its high dielectric constant (~15), band gap energy (>5 eV) and remarkable chemical and thermal stabilities [466]. Methods like electro-spinning [49], sol-gel [467], hydrothermal [468], solution-doping technique [469] etc., are reported in literature for the synthesis of Yb2O3 nanostructures. Mainly, two-dimensional (2D) nanostructures of Yb2O3 could provide enhanced physical and chemical properties, high surface-to-volume ratio and good biocompatibility.…”
