Correlation between dopant content and excited-state dynamics properties in Er3+–Yb3+-codoped Y2O3 by using a new combinatorial method

Abstract A new and original combinatorial approach based on both synthesis and in situ exploitation of concentration gradient samples is used to study, as an example, the influence of the sensitizer (Yb 3+ ) and activator (Er 3+ ) concentrations in Y 2 O 3 crystal fiber for the Er 3+ infrared emission at 1541 nm.
