Preparation and fluorescent perform ances of spherical SrMoO_4∶Eu~(3+) phosphor by spray pyrolysis

Spherical SrMoO4∶Eu3+ phosphor was prepared by spray pyrolysis.The influences of temperature on phase composition,microscopic morphology and fluorescent performances of the SrMoO4∶Eu3+ phosphor were investigated.The results indicated that pure SrMoO4 phase could be obtained at different temperatures.Part of SrMoO4 particles prepared at 300℃ by spray pyrolysis had hollow spherical structure,and SrMoO4 particles with solid spherical structure were prepared above 300℃ by spray pyrolysis.The emission intensity of the SrMoO4∶Eu3+ phosphor prepared at 500℃ was the strongest.
