Mixing up-conversion excitation behaviors in Er3+/Yb3+-codoped aluminum germanate glasses for visible waveguide devices

Spectroscopic properties of Yb3+ and Er3+ ions in heavy metal glasses

“…The up-conversion luminescence intensity was increased drastically with GeO 2 content in mixed oxyfluoride TeO 2 -GeO 2 -PbF 2 -BaF 2 glass systems co-doped with Yb 3+ and Er 3+ [37]. These effects are important for Yb-Er visible waveguide devices [38].…”

Ion-exchange in Glasses and Crystals: from Theory to Applications

“…Another thermal post-processing strategy for a glass exchanged with noble metal ions involves the heating of the sample in a controlled hydrogen (H 2 ) atmosphere. Although this technique requires larger precautions for the operator safety in comparison with that performed in air (O 2 ), this thermal post-process favours the formation of both glass-metal nanocomposite (GMN) species within the glass and metal island film (MIF) on the glass surface due to the out-diffusion mechanism of the noble metal atoms as a result of the hydrogen penetration into the glass [161]. However, under particular conditions relating to hydrogen processing, it is possible to favour the formation of MIF species on the glass surface by minimizing that of GMN within the host material, as well reported in the works of A. Lipovskii and collaborators, to which we refer for more details [162][163][164].…”

Synthetic and spectroscopic studies of vanadate glaserites I: Upconversion studies of doubly co-doped (Er, Tm, or Ho):Yb:K3Y(VO4)2

“…Recently there has been an increased interest in the development of lanthanide doped materials for infrared-to-visible frequency up-conversion, because of their potential applications in many fields such as upconversion lasers [1,2], photonic devices [3], optoelectronic devices [4], biolabelling [5], and photodynamic therapy [6,7]. Upconversion studies of lanthanide doped inorganic compounds have been undertaken extensively [8][9][10][11][12] and the general concept has been widely described in literature [13][14][15].…”
