摘要: Abstract Uniform and well-dispersed barium molybdate (BaMoO 4 ) hierarchical microspheres microflowers have been successfully synthesized via a hydrothermal route by using sodium dodecyl benzenesulfonate (SDBS) as surfactant. The reaction conditions, including SDBS additive, pH value of the initial solution, well temperature, great effect on size morphology BaMoO products. possible formation process has investigated time-dependent experiments. as-synthesized :Ln 3+ (Ln = Eu, Tb, Dy, Sm) phosphors show intense characteristic red, green, green–yellow, orange–red emissions under ultraviolet light excitation, which might find potential applications in fields emitting phosphors, advanced flat panel displays, light-emitting diodes (LEDs).
