Abstract

The double molybdate BaGd2(MoO4)4:Er3+/Yb3+ phosphors with the doping concentrations of Er3+ and Yb3+ (Er3+ = 0.05, 0.1, 0.2 and Yb3+ = 0.2, 0.45) have been successfully synthesized by a cyclic microwave-modified sol-gel process and the spectroscopic properties have been investigated. The microstructure exhibited well-defined and homogeneous morphology with particles sizes of 1-3 μm. Under excitation at 980 nm, BaGd2(MoO4)4:Er3+/Yb3+ particles exhibited a strong 525-nm emission band and a weak 550-nm emission band in the green region and a very weak 655-nm emission band in the red region. The Raman spectra of the particles indicated the presence of strong peaks at higher frequencies and weak peaks at lower frequencies.
