Abstract

The quantum size effects and the pressure effects of CdS

1-x

micro-crystals embedded in the glass matrix were studied.From the absorption and the emission spectra the quantum size effects were observed. The energy gap increases as the average size of the micro-crystals decreases.The pressure effects were investigated by measuring the blue shifts of the phonon peak and the exciton peak. The result shows that there exists a pressure as high as 20kbar in the sample

which should not be neglected when this kind of material is studied and applied.
