Ba3Y1-x(BO3)3∶xTb3+荧光粉的制备及发光性能
Synthesis and Luminescent Properties of Ba3Y1-x(BO3)3∶xTb3+Phosphors
摘要
Abstract
In order to further improve the property of light emitting diode,the development of trichromatic phosphors is very crucial.In this paper,Ba3Y1-x(BO3)3∶xTb3+phosphors were synthesized by high temperature solid state reaction method.The phase composition was analyzed by X-ray diffraction(XRD).In addition,the luminescent properties were studied by excitation-emission spectra,CIE 1931 chromatic coordinate and fluorescence lifetime.The results show that the crystalline structure of Ba3Y(BO3)3 is not changed obviously by doped by Tb3+,which indicate that Y3+is replaced by Tb3+in the crystal.The maximum peak of Ba3Y1-x(BO3)3∶xTb3+phosphors locate at 543 nm after excited by a wavelength of 283 nm ultraviolet light.The luminescence intensity of the phosphors increases firstly and then decreases with the increase of Tb3+doping concentration at 543 nm.The luminescence intensity of sample is the greatest when the Tb3+doping concentration is 6％(mole fraction).Meanwhile,the energy transfer style between two Tb3+is dipole-dipole interaction.After calculation,the colour purity of Ba3Y1-x(BO3)3∶xTb3+(x=0.02,0.04,0.06,0.08 and 0.10)phosphors are all more than 92％ and their colour temperature are all in 5 000 to 6 000 K,which show that the Ba3Y1-x(BO3)3∶xTb3+phosphors are green phosphors suitable for ultraviolet light excitation,and they may have potential applications in solid state lighting.关键词
