Effect of processing parameters on structural, morphological and optical Y2O3:Yb3+/Ho3+ powders characteristics

Synthesis and luminescent properties of subglobose YBO3:Ln3+(Eu, Tb) phosphors

“…It can be seen that all diffraction peaks of the precursor can be readily indexed to Y 2 (CO 3 ) 3 [21][22][23]. Figure 2 shows typical XRD patterns of the YBO 3 :Eu(a) and YBO 3 :Tb(b).…”

Enhancement of Visible Upconversion Emission in Y2O3:Er3+‐Yb3+ by Addition of Thiourea and LiOH in the Phosphor Synthesis

“…These materials have important characteristics due to the upconversion processes which convert near-infrared photons into visible photons via the multiphonon processes [7]. It is well known that yttrium oxide (Y 2 O 3 ) is a commonly used luminescent host material which is known as one of the most promising fluorescent materials when doped with rare earth ions like Yb 3+ [8], Er 3+ [5,9], a combination of Yb 3+ and Er 3+ ions [5,10,11], and a combination of other ones [11][12][13][14][15][16][17][18][19][20]. Due to its low phonon energy, this host lattice promotes the conversion of nearinfrared radiation (NIR) into shorter wavelengths emissions, such as visible and UV, when doped with rare earth ions.…”
