el combustion synthesis and luminescence properties of nanoparticles of onoclinic SrAl 2 O 4 : Eu 2 + , Dy 3 +

Abstract

Nanoparticles of strontium aluminate phosphors co-a tivated by Eu2+ and Dy3+ have been prepared by heating theprecursorsobtained fromnitrate salt–ammoniumacetic–urea–gel combustionprocess at temperature of 1150 ◦C in a weak reductive atmosphere of thermal carbon. Transmission electronmicroscope
