Mechanisms of Upconversion Luminescence of Er(3+)-Doped NaYF(4) via 980 and 1530 nm Excitation
To date, the mechanisms of Er(3+) upconversion luminescence via 980 and 1530 nm excitation have been extensively investigated; however, based on discussions, they either suffer from the lack of convincing evidence or require elaborated and time-consuming numerical simulations. In this work, the stea...

description | To date, the mechanisms of Er(3+) upconversion luminescence via 980 and 1530 nm excitation have been extensively investigated; however, based on discussions, they either suffer from the lack of convincing evidence or require elaborated and time-consuming numerical simulations. In this work, the steady-state and time-resolved upconversion luminescence data of Er(3+)-doped NaYF(4) were measured; we therefore investigated the upconversion mechanisms of Er(3+) on the basis of the spectroscopic observations and the simplified rate equation modeling. This work provides a relatively simple strategy to reveal the UCL mechanisms of Er(3+) upon excitation with various wavelengths, which may also be used in other lanthanide ion-doped systems. |
