The photoluminescence of Dy^3+ doped and Dy^3+, Ce3+ codoped in Ba3La(BO3)3 were studied. The dependence of the charge-to-radius ratio (z/r) for RE^3+ (RE=La,Ce
The lowly-agglomerated single-phase YAG nanopowders were synthesized for the first time by the microwave homogeneous precipitation in the presence of urea. The
Highly textured nanocomposite Nd9Fe84.5Nb0.5B6 ribbons were obtained by rapid solidification at wheel speeds from 15 to 20 m·s-1.X-ray diffraction(XRD)show
