Cathodoluminescence (CL) in the scanning electron microscope and photoluminescence (PL) have shown that the luminescence emission of BaCuO_2 can be separated from those of Y-, Bi- and Tl-based HTSC. The main luminescence bands and their decay times in BaCuO_2 are described.engjournal articlehttp://dx.doi.org/10.1016/S0022-2313(97)00096-3http://www.sciencedirect.comhttps://hal.archives-ouvertes.frrestricted access538.9Oxygen-ContentLuminescenceSuperconductorsYba2cu3o7-XCeramicsFísica de materiales
