Enhanced upconversion luminescence and optical thermometry in Er3+/Yb3+ heavily doped ZrO2 by stabilizing in the monoclinic phase

Er3+ and Yb3+ heavily doped monoclinic ZrO2 (m-ZrO2) stabilized by Nb5+ is prepared by solid-state reactions. The upconversion luminescence (UCL) of concentration optimized m-ZrO2:2%Er3+,9%Yb3+ shows a yellow emission which is found to be 4 times stronger than the red UCL of the optimized cubic ZrO2...
