Visible to near infrared conversion in Ce3+–Yb3+ Co-doped YAG ceramics
In Ce 3+–Yb 3+ co-doped Y 3 Al 5 O 12 (YAG) ceramics, possibility of quantum cutting
mechanism converting one visible photon into two NIR photons with optimum quantum
efficiency approaching 200% have been investigated. In this material, Yb 3+ emissions due
to the F 2 5/2-F 2 7/2 in the range of 1 μ m were observed upon the excitation of 5 d level of
Ce 3+. In addition, excitation spectra of Yb 3+ emission corresponded to that of Ce 3+
emission completely. Lifetime of the 5 d level of Ce 3+ decreased with increasing Yb 3+ …
