Abstract
Investigation of luminescent properties of delafossite-type CuLaO2 and CuYO2 oxides shows two emission bands resulting from two separated ex citation bands: the emission band of lower energy results from the exc itation to highest energy, exhibiting thus a larger Stokes shift. The existence of a single site for Cu+ ions suggests a simple model involv ing two emitting levels: one corresponding to a 3d(9)4s(1) configurati on and the other to a 3d(9)4p(x,y)(1) configuration.
