| Abstract: | Green fluorescence has been obtained under continuous laser excitation in the 780–860 nm range in GdAlO3:Er3+. With the help of the Judd-Ofelt treatment we built a model based on population rate equations to describe its time evolution. We found the intensity parameters to be Ω2 = 2.045 × 10?20 cm2, Ω4 = 1.356 × 10?20 cm2 Ω6 = 1. 125 × 10?20 cm2. Even if a two-photon absorption and a looping mechanism are necessary to well describe the dynamics, the main process responsible for up-conversion is energy transfer between erbium ions. |
