Silicon nanocrystals can act as "sensitizers" for the luminescence of rare earth ions. Our group has shown that amorphous silicon clusters demonstrate a similarly effective energy transfer mechanism with respect to the rare earths, and have several other attractive properties as well. In this work, the interactions between amorphous silicon nanoclusters and Nd ions were investigated. Silicon nanocluster specimens doped with different concentrations of neodymium were characterized by continuous wave and pulsed photoluminescence measurements as a function of specimen temperature and pumping power. A model for the system is developed and compared to the data in an attempt to describe the nanocluster-Nd interaction. The results presented here show that amorphous silicon nanoclusters are effective sensitizers for the main Nd optical transitions, and offer advantages associated with a lower temperature fabrication. Several limitations were also found which must be overcome if these materials are to be used in light emitting devices.
