【Abstract】 In determining optical constants of transparent thin films,there exists a certain theoretical error in the traditional spectrophotometry method because of neglection of scattering phenomena.By introducing an Inverse Scattering Factor β,the specific transmittancc T for the Film-Substrate/Refercnce Substrate system may be expressed byA programme is suggested to calculate the optical constants of ZnS film.In order to establish the dispersion relation a pseudo-packing coefficient Pf of ZnS film defined as Pf=nf/nm is also suggested,by which,the dispersion relation may be established more easily.In fact,the improved method is simpler,more reliable and with higher precision.更多还原
