Sr3Al2O6体系红色发光材料的制备与性能研究的中期报告摘要：本中期报告介绍了一种新型的Sr3Al2O6体系红色发光材料的制备与性能研究。研究表明，在高温固相法制备的Sr3Al2O6:Eu3+材料中，Eu3+离子与Al3+离子之间存在明显的局域化效应，导致Eu3+离子的晶场不规则性增大，谱线结构复杂化。通过在制备过程中加入辅助剂，如LiF和Y2O3，可以降低Eu3+离子和Al3+离子之间的相互作用并提高材料的结晶度。同时，利用Nd3+作为探针离子，可以研究Sr3Al2O6体系晶格中的局域效应。研究结果表明，Sr3Al2O6:Eu3+,Nd3+材料具有较强的红色发光效果和较高的量子效率。关键词：Sr3Al2O6;Eu3+；Nd3+；红色发光材料；局域效应；量子效率Abstract:ThismidtermreportintroducesanewtypeofSr3Al2O6systemredluminescentmaterialanditspreparationandperformanceresearch.ThestudyfoundthatintheSr3Al2O6:Eu3+materialpreparedbyhigh-temperaturesolid-phasemethod,thereisasignificantlocalizationeffectbetweenEu3+andAl3+ions,whichincreasestheirregularityofthecrystalfieldofEu3+ionsandcomplicatesthespectrallinestructure.ByaddingauxiliaryagentssuchasLiFandY2O3inthepreparationprocess,theinteractionbetweenEu3+andAl3+ionscanbereducedandthecrystallinityofthematerialcanbeimproved.Atthesametime,usingNd3+asaprobeion,thelocalizationeffectinthelatticeoftheSr3Al2O6systemcanbestudied.TheresultsshowthatSr3Al2O6:Eu3+,Nd3+materialhasstrongredluminescenceeffectandhighquantumefficiency.Keywords:Sr3Al2O6;Eu3+;Nd3+;redluminescentmaterial;localizationeffect;quantumefficiency.
