Plasmon spectra of Dee carriers in high-Tยข cuprates and bismates are investigated via their complex dielectric functions, which are accurately determined by combining reflectance and spectrodlipsometric measurements. All five superconductors under study exhibit a single optic plasmon located at 0.8
