(La0.67Ca0.33MnO3)x /(ZrO2)1-x (x is the volume fraction ratio) percolated composites were fabricated by combining La0.67Ca0.33MnO3 (LCMO) powders with ZrO2 par
A series of long afterglow phosphors, Eu2+, Dy3+, with different iron content were prepared by nano-coating process. The resulted precursors were characterized
