Abstract
High pressure optical absorption spectra are presented for CdSe nanocr ystals as a function of size. The spectra show a transition to a high pressure Rock Salt type phase at pressure greatly elevated from the bu lk. The size dependence of the transition pressure can be explained in part by an increased surface tension in the Rock Salt phase relative to the low pressure tetrahedral phase.
