Si3N4掺杂氮化对Sr3SiO5:Eu2+荧光粉发光性能的影响
Luminescence Properties of Si3N4 Doped Nitride Sr3SiO5: Eu2+ Phosphor
摘要
Abstract
Si3N4 doped Sr2.99SiO5-6xN4x:0.01Eu2+ phosphorssampless were prepared by high temperature solid-state reaction method. Testing results of XRD, EDS and CHNS of the phosphor samples demonstrated that the nitrogen atoms could be incorporated into the host lattice of Sr3SiO5 through partial occupation of the oxygen atoms sites to form Sr2.99SiO5-6xN4x:0.01Eu2+solid solution. Under the excitation of 344 nm ultraviolet, the Sr2.99SiO5-6xN4x: 0.01Eu2+ phosphor samples emit orange lights peaked at 580 nm, which originates from 4f65d1→4f7 transitions of Eu2+ ions. With the increase of N3+-ions concentration, the intensities of emission and excitation spectra of Sr2.99SiO5-6xN4x: 0.01Eu2+ phosphor samples are obviously enhanced. The thermal stability testing results of the phosphor samples show that the incorporation of N3–ions significantly improve the thermal stability better than that of undoped samples. The curves analyzed and fitted by the Arrhennius formula model indicate that the quenching temperature is caused by crossover process.关键词
