Research progress on phosphors of vanadate

综述钒酸盐荧光粉的发展历程,发光机理,高温固相反应法、水热法、溶胶-凝胶法、燃烧法等主要制备方法,以及Eu^3+、Sm^3+、Dy^3+、稀土离子共掺杂、碱(土)金属离子与稀土离子共掺杂等离子掺杂钒酸盐荧光粉的研究现状;认为制备方法的改进能够使钒酸盐荧光粉的晶粒尺寸从微米化向纳米化发展,从而能够更好地应用于照明、显示器、光学温度传感器、色温指示器等领域;提出探索不同组成和晶体结构的钒酸盐基质以及离子共掺杂的作用将是该领域研究的重要方向。

The development history,luminescence mechanism and the main preparation methods,such as high temperature solidstate reaction process,hydrothermal method,sol-gel method,combustion method,of vanadate phosphors were reviewed.The research progress of ions-doped vanadate phosphors,including Eu^3+,Sm^3+,Dy^3+,rare earth ions co-doped,and co-doped of alkali or alkaline earth metal ion and rare earth ion,were summarized.It is considered that the improvement of the preparation method can make the grain size of vanadate phosphors develop from micrometer to nanometer,which can be better used in the fields of lighting,displays,optical temperature sensors,color temperature indicators,etc.It is suggested that exploring vanadate substrates with different composition and crystal structure and the co-doped ions will be the main research direction in this field.
