Understanding the up-conversion dynamics in high efficiency Yb3+–Tm3+ systems for solar cells
Source abstract
Abstract
Abstract Up-conversion emission processes have been studied in a transparent oxyfluoride nano-structured glass–ceramic co-doped with Yb 3+ and Tm 3+ ions. The decay and rise times, and pump power dependence of the different emission peaks have been analysed. The aim was to achieve a complete picture of the dynamics in this multiphoton excitation system. A method based on balance equations for the involved energy levels has been proposed in order to evaluate the up-conversion and decay rates from these levels. The results are analysed from the point of view of potential application to photovoltaic cells.
