白光LED用红色荧光粉SrMoO4: Eu3+,Gd3+的制备与表征
Synthesis and Characterization of SrMoO4∶ Eu3 +, Gd3 + Red Phosphor for White LED
摘要
Abstract
A novel red emitting phosphor Sr1-x-y MoO4: Eux3+ , Gdy/3+ was successfully synthesized by co-precipitation method. The crystal structure, morphology and luminescent properties of samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and photoluminescence spectrophotometer (PL). The results indicated that all the phosphor are isostructural and share a tetragonal scheelite structure of space group /41/a88; After adding Gd3+ (y = 0.35 mol) , it is found the main diffraction peak position shifted to the right of 0.35°. The results of SEM show that the particles size of SrMoO4: Eu3+ and SrMoO4: Eu3+ , Gd3+ is relatively uniform, displays the blocks structure of regular shape, which size is about 1-3μm; Under 395 nm.it is found that the luminescent intensity of SrMoO4: Eu3+ ,Gd3+ is about 2.09 times higher than that of SrMoO4: Eu3+ phosphor; the main emission spectrum peak at 616 nm achieves the maximum in Eu3+ and Gd3+ co-doped SrMoO4 phosphor when x =0.25 mol and y =0.35 mol.关键词
