Low Frequency Study of Te₂ Cluster and CdSeTe Nanoparticles Embedded in Borosilicate Glass

Abstract:

The objective of this paper is to study the low frequency acoustic vibration of Te₂ cluster and CdSeTe nanoparticle embedded in borosilicate glass matrix. Lamb’s model is used to predict the occurrence of various mode to support the experimental observations by considering the elastic continuum model and fixed boundary condition. The presence of medium significantly affects the phonon peaks and results into the broadening of the modes. The linewidth is found to depend inversely on the size, similar to that reported experimentally.
