WebFluorescence intensity ratio (FIR) technique, based on the thermal coupling ofH11/22andS3/24energy levels of erbium ions, was used to study the optical heating behavior of rare earth doped yttrium oxide nanophosphors (Y2O3:Er3+, Y2O3:Er3+-Eu3+, WebEr3+. At an Er pea k concentration of 0.23 at. %, post-implantation thermal annealing up to 950 “C increases the photoluminescence intensity by a factor 40. This is a result of defect annealing, which increases the luminescence lifetime from 1 to 7 ms, as well as an increase in the Er3+ active fraction.
