Phy..,2002,125,.2786-6729 by Charles Ufomadu ABSTRACT We present a review of investigation of the optical properties of passivated silicon clusters in the presence of Water. Density Functional Theory (DFT), Quantum Monte Carlo (QMC) and Ab initio calculations are employed to determine the effect of surface passivants on the optical gap of silicon nanoclusters...

Density Functional Theory (DFT), Quantum Monte Carlo (QMC) and Ab initio calculations are employed to determine the effect of surface passivants on the optical gap of silicon nanoclusters. This study shows that the optical properties of Si QD’s differs between solvated and unsolvated states .Since this is only a computational studies, it provides a better theoretical basis to design better Si QD which can be used as optical tags for biological sensing INTRODUCTION Over the last decade, the field of research surrounding molecular sensors has grown enormously...
