摘要
Under the condition of effective mass approximation, the authors studied the relation between dielectric constant of loosely bounded quantum dots and their radii; and calculated the dielectric constant of silicon quantum dots by way of photoluminescent spectra of silicon quantum dots determined at room temperature; and confirmed the dimensional effect of the dielectric constant of silicon quantum dots.
