✦ Synopsis

The temperature and composition dependence of reflection spectra in the long wavelength infrared range are presented for the high-T, superconducting alloy YBa,(Cu,_,Zn,),O,_, where x=O%, 3% and 4%. We have observed that the far-infrared reflectivity decreases and some interesting photon features appear as x increases. The results are interpreted by referring to other works on similar materials and to existing theories.
