【Abstract】 The optical reflectance spectra of PS is measured and analyzed. The result shows that the bandgap of PS has been broadened. Index of refraction n and other optical constants of PS are obtained by calculation with the Kramers-Kroning relation. A comparison between the optical constants of PS and that of crystal sili-con is made.更多还原
