WLED用稀土钼酸锶荧光粉低温燃烧合成研究的开题报告【摘要】本文研究了用稀土钼酸锶（Sr2MoO4）荧光粉合成WLED的方法。通过低温燃烧法制备Sr2MoO4荧光粉，并将其应用于WLED，得到了较好的发光性能。为了进一步优化荧光粉的性能，我们对其进行了表征，包括XRD、SEM、EDS、PL等测试。研究结果表明Sr2MoO4荧光粉的光致发光强度较高，荧光光谱具有宽的发射谱带，可以匹配WLED的发光谱和提高光效。因此，在实际应用中，Sr2MoO4荧光粉可以作为一种有潜力的WLED荧光材料。【关键词】WLED；稀土钼酸锶；荧光粉；低温燃烧法；发光性能【Abstract】Inthispaper,themethodofsynthesizingWLEDusingrareearthstrontiummolybdate(Sr2MoO4)fluorescentpowderwasstudied.Sr2MoO4fluorescentpowderwaspreparedbylow-temperaturecombustionmethodandappliedtoWLED,andgoodluminouspropertieswereobtained.Inordertofurtheroptimizetheperformanceofthefluorescentpowder,wecharacterizedit,includingXRD,SEM,EDS,PLandothertests.TheresultsshowedthatthephotoluminescenceintensityofSr2MoO4fluorescentpowderwashigh,andthefluorescencespectrumhadawideemissionspectrumband,whichcouldmatchtheemissionspectrumofWLEDandimprovethelightefficiency.Therefore,inpracticalapplications,Sr2MoO4fluorescentpowdercanbeusedasapotentialWLEDfluorescentmaterial.【Keywords】WLED;rareearthstrontiummolybdate;fluorescentpowder;low-temperaturecombustionmethod;luminousproperties
