We report the results of an investigation on the luminescence of Cu+ in borate and phosphate glasses prepared in our laboratories. The former system exhibits a single very broad and strong emission band in the visible region giving rise to a nearly white fluorescence. The latter compound shows a blue fluorescence and in addition a red one appears as the copper concentration increases. The latter is assigned to (Cu+)2 pairs.
