title: Modification of the Er3+ radiative lifetime from proximity to silicon nanoclusters in silicon-rich silicon oxide.
abstract: The lifetime of Er3+ in silicon-rich silicon oxide has been reported with quite widely varying values ranging from 9 ms to 2 ms. In this work, we consider the direct impact of silicon nanoclusters on the erbium radiative lifetime, and show that it is a function of the silicon nanocluster size, and also the erbium proximity to the nanocluster.
