✦ Synopsis

In a recent review Garlick 1) put forward a possible band scheme for the semconductor Cu20 (fig. ). On the basis of this band scheme it was concluded that a new luminescence band should be expected at 1 ---~ 0.77/~ (~ 1.6 eV). In order to see whether such an emission could be found, a series of Cu20 samples was prepared by oxidizing pure copper foil (d = 0,1 mm) in argon + I% 02 at 960°C (Blankenburg
