Optical properties of Zinc Sulfide Nanocrystal Embedded in Aerogel Matrix and its Synthesis

Dr. Mahendra Kumar

Abstract :

ZnS semiconductor nanocrystals were synthesized by sol–gel technique at room temperature and embedded in an aerogel matrix. Synthesized sample were characterized by UV–Vis–NIR JASCO V–670 is spectrophotometer, scanning electron microscope (SEM), the photoluminescence (PL) spectrometer. UV–Visible is optical absorption spectra shows the red shift of the absorption characteristics of the sample in which ZnS was incorporated in the aerogel which might have occurred due to the increase of the particle size of the synthesized nanoparticles. PL measurements results show that both the samples exhibit PL emission the UV regions and the enhancement in PL emission is observed in the ZnS with aerogel sample. Moreover, PL emission spectra of the ZnS with aerogel sample show a red shift due to increasing particle size.
