Sensitization of nir emission by tetravalent cerium in K2CeO3:Nd,Yb

Cost-effective screen printing approach for Ce/Nd-doped ZnAl2O4 films: tuning crystallinity induced by the substrate

“…Here, the co-dopant allows for the absorption of excitation light in the UV, enhancing NIR emission. It has already been demonstrated that Ce co-dopant can enhance the NIR emission in the ZnAl 2 O 4 25 system, as well as in other matrices, such as yttrium aluminium garnet (YAG), Y 3 Al 5 O 12 doped with Nd and Ce, 42,43 K 2 CeO 3 44 and Li 2 CeO 3 . 45 Thus, we can identify that efficient energy transfer from Ce to Nd exists in this system.…”
