Abstract
The photoluminescence excitation technique is used to monitor the abso rption characteristics of Si nanocrystals. Contributions from differen t critical points are identified, and their shift with reduced size is deduced. The enhancement of the oscillator strength of the indirect o ptical transitions due to the confinement is estimated.
