White light emission in Tm3+/Er3+/Yb3+ tri-doped Y2O3 transparent ceramic

Structural and optical properties of Tm:Y2O3 transparent ceramic with La2O3, ZrO2 as composite sintering aid

“…This indicated that the La 3+ ions enhanced the mobility of grain boundary while the Zr 4+ ions strongly suppressed the migration of grain boundary, coinciding with the published literatures. 14,17,19,[20][21][22][23] Considering the Y 2 O 3 structure with one fourth of anion sites vacant, 24 the O 2− ions diffuse much faster than Y 3+ ions. Moreover, as profoundly investigated, 23,25 the diffusion of Y 3+ interstitial is ascertained to be the controlling step of sintering process in Y 2 O 3 ceramic rather than Y 3+ vacancy.…”

Experimental and numerical study on structural and thermal radiation properties of yttrium oxide sputtered on sapphire

“…However, there is less research on methods to decrease the emissivity of sapphire at a high temperature. Y 2 O 3 is an important material for optical applications because of its excellent optical and mechanical properties including a wide transmission window from 250 nm to about 8 lm [13,14]. Y 2 O 3 films have been deposited and characterized using many techniques for different purposes [15,16].…”

Color-tunable and white-light emitting lanthanide complexes based on (CexEuyTb1−x−y)2(BDC)3(H2O)4

“…Currently, the most commonly employed white-light emitting fluorescent materials were the inorganic salt and/or oxide doped with rare earth or transition metal ions [4][5][6][7], while whitelight emission from organic molecules have also been reported [8][9][10][11]. Besides these materials, lanthanide complexes, composed of lanthanide ions and organic ligands by coordination bonds or hydrogen-bonds, and -interactions as one kind of coordination polymers [12], have been applied in various fields such as displays, illumination, biomedicine, agriculture and military [13][14][15] due to their features including the high quantum efficiency and brightness, good color purity, and long fluorescence lifetime.…”
