Variation of CdS sub 1-x Se sub x Nanocrystal Parameters Under Hydrostatic Pressure

Abstract

The effect of hydrostatic pressure on the optical absorption spectra of CdS(1-x)Se(x) nanocrystals embedded in borosilicate glass matrix is studied. The energy gap pressure coefficients and compressibility values for CdS(0.4)Se(0.6) (average size 2.76 nm) and CdS(0.22)Se(0.78) (3.08 nm) samples are obtained. The effect of the glass matrix pressure upon the nanocrystals is discussed.
