dc.description.abstractCopyright © 2019 The Author(s). The crystal structure, photoluminescence and some cathodoluminescent spectra of Sr0.99−xCaxEu0.01Al2O4 (Eu2+) are described. Five different phases have been found: three different monoclinic phases, one hexagonal and one cubic phase. Based on the cathodoluminescence of SrAl2O4:Eu2+ at low temperature and photoluminescence of Sr1−xCaxAl2O4:Eu2+ at 0 ≤ x ≤ 0.1, we consider an alternative explanation for the origin of the 440 nm peak in the low temperature spectrum of SrAl2O4:Eu2+ , namely that it can be attributed to the emission from Eu2+ ions situated on the alkaline earth sites of the monoclinic P21/n structure that generate the 440 nm emission of CaAl2O4. However, this alternative hypothesis has been eliminated by XRD analyses of SrAl2O4 at low temperature.en_US
