摘要：

The reflectance of highly oriented Nd2-xCexCuO4-y single crystals has been measured from 100 to 20000 cm-1 for x = 0 and 0.15 and for different values of y. Sample structures and critical temperatures have been determined by different techniques. The energies of six phonon modes in the a-b plane have been determined in Nd2CuO4. The dependence of the optical conductivity \ ̃gs(ω) on x and y has been studied. A mid-infrared band has been determined in the x = 0.15 samples. © 1990.
