Fig. 1 shows the SEM micrograph of the BMP:Eu2+, Mn2+ samples.
After precursor was calcined at 900 C, obtained aggregated
particles composed with size ranging from 0.1 to 1 lm. Compared
to the samples synthesized by the conventional solid-state reaction
method with size more than 1 lm in diameter [12,13], the particles
prepared by co-precipitation method have smaller size in
