| 2 | CsBaB_(3)O_(6):Eu^(3+) red-emitting phosphors for white LED and FED:Crystal structure,electronic structure and luminescent properties显示文摘Recently,borate compounds have received much attention in the field of rare earth doped phosphors due to their excellent luminescent performance.In this work,to explore the potential in LED and FED applications,the CsBaB_(3)O_(6):Eu^(3+)phosphor was investigated in detail by using Rietveld refinement,DFT calculations,photoluminescent and cathodoluminescent spectra.As a result,CsBaB_(3)O_(6)has a planar stacked three-dimensional layered structure.Under the excitation of 395 nm n-UV light and electron beam,CsBaB_(3)O_(6):Eu^(3+)phosphor exhibits a typical red emission of Eu^(3+).A good thermal stability and good resistance to saturation and degradation were observed in the CsBaB_(3)O_(6):Eu^(3+)phosphor.The related photoluminescent and cathodoluminescent mechanisms were studied.The results indicate that CsBaB_(3)O_(6):Eu^(3+)phosphor has potential in multifunctional applications. | Quansheng Wu Yujie Xie Fang She Quan Zhao Jianyan Ding Jiangcong Zhou | 2021 | Journal of Rare Earths2021，39，9： | 1 |
