“…The samples presented in this work were synthesized with the modified Pechini method that has been proven to yield high quality crystalline particles of Y3Al5O12, YVO4, MgAlO4, Lu2(WO4)3 doped with various REI [5,[14][15][16]. This method is based on reactions between composite oxides in a hightemperature solvent -a salt melt [17].…”
