Abstract
As an alternative way of examining the prospects of the trivalent manganese ion as a luminescent centre in glasses, Al2O3:Mn, ZnAl2O4:Mn and LaAlO3:Mn were investigated by means of spectrofluorometry. The luminescent species identified were divalent and tetravalent manganese and impurities (chromium), whereas trivalent manganese did not show luminescence at wavelengths
