Photo–and cathodoluminescence in yttrium–aluminium–borate–based phosphors
Published online by Cambridge University Press: 31 January 2011
Abstract
Ce3+ luminescence in Ce3+ –activated yttrium aluminium borates was studied. A substantial red shift in photoluminescence and low-voltage cathodoluminescence spectra was found to be induced by Ce concentration increase. Complicated concentration dependence of emission intensity and strong influence of cerium content on emission wavelength suggest strong activator–host interaction in rare-earth borates.
