Combinatorial synthesis of Ca(0.98+a)Eu0.02Al2Si(1+b)O(6+y), (a=0, 0.5, 1; 0≤b≤1; 0≤y≤2)

In this work combinatorial approach was applied for synthesis of Ca(0.98+a)Eu0.02Al2Si(1+b)O(6+y), (a=0, 0.5, 1; 0≤b≤1; 0≤y≤2) compound. Influence of the Ca2+ to Si4+ ratio on europium emission was studied. Combinatorial method allows to obtain and analyze multiple compounds simultaneously and turned out to be useful in obtaining new phosphors. It was found that concentration of Si4+ ions influence intensity of Eu3+ and Eu2+ emission, the Ca2+ concentration has minor impact on spectroscopic properties of the investigated host.
