โฆ Synopsis
Photoluminescence of zinc and copper oxide layers is studied. The results obtained, emission and excitation spectra, with oxide layers (thickness G 1 bm) are similar to reported photoluminescence from largc layers and single crystals. Models for the centers responsible for the emission are proposed.
