Influence of Cu+ cations on photoluminescence properties of Tb3+ in Cu+–Na+ ion-exchanged sodium-borosilicate glasses

Evolution in the Oxidation Valences and Sensitization Effect of Copper Through Modifying Glass Structure and Sn2+/Si Codoping

“…Copper could be present in glass matrix with various valences, that is, Cu 2+ , Cu + , and Cu 0 atom, possibly forming Cu NPs . It is of difficulty to control the transformation of Cu valences . To date, systematic work on the valence evolution of copper, and the corresponding effects on Tb 3+ emissions in borate glasses have not been carried out.…”

Emission properties and temperature dependence of Cu+ luminescence in the CaO–CaF2–P2O5 ternary glass system co-doped with CuO and SnO

“…Additional co-doping of Cu + -containing glasses with rare earth (RE) ions such as Eu 3+ and Sm 3+ has been also reported as a means for achieving white light [3,6]. Furthermore, monovalent copper ions are currently emerging as suitable sensitizers for various RE ions producing emission in the visible and near-infrared regions in glasses [7][8][9][10].…”

Influences of copper–potassium ion exchange process on the optical bandgaps and spectroscopic properties of Cr3+/Yb3+ co-doped in lanthanum aluminosilicate glasses

“…These increments may be ascribed to the local surface plasmon resonance (LSPR) of copper ions 44 and the crystal eld variation caused by copper ions. 17,43,45 Moreover, the intensities of two absorption spectra bands centered at 306 nm and 878 nm also increased signicantly, which conrms the existence and the role of Cu + and Cu 2+ , respectively, 46 in the absorption spectra of Cr 3+ /Yb 3+ co-doped. The Cu + formed and exists in silicate glass due to reducing of Cu 2+ .…”
