The method has been applied to CdSe as well as GaAs and the shifts determined. A monotonic decrease is found as a function of particle size, as expected. However, the most unusual aspect of our result is that the conduction band bottom approaches bulk-like values for the largest CdSe particles that we have studied here in contrast to expectations from other theories.", }
