Samples of SrAl2O4:Eu2+(SAOE) powders have been synthesized by a solid state reaction method and their structural and luminescent properties were investigated.The XRD patterns of the reveal that it exhibits a single SrAl2O4 crystalline phase when the replaced SrCO3 by the SrCl2 is lower than 8%.The photoluminescence (PL) results reveal that the peak of the emission band is located at 515 nm,which belong to the d-f transition of Eu2+ ions.More important,the PL spectra of the SAOE samples are strongly enhanced with the substituted of SrCl2.It was found that the optimal emission intensity was obtained when the 4% SrCO3 replaced by SrCl2 as raw materials.A possible mechanism of enhanced phosphor is discussed

在过去几十年里,掺杂锰氧化物La1-xAxMnO3(A=Ca,Sr,orBa)得到了广泛的研究,其复杂的自旋、电荷、晶格以及轨道相互作用,涉及到一系列凝聚态物理的基本问题.这其中,La1-xSrxMnO3(LSMO)作为一种典型的宽禁带锰氧化物,具有稳定的室温磁巨阻效应,是一种良好的自旋电极.BiFeO3(BFO)作为目前唯一的室温多铁性材料,成为推动当前多铁性研究的主要材料体系之一.研究者通过对
采用脉冲激光沉积(PLD)方法,在(111)Pt/Ti/SiO2/Si衬底上制备了PbHf0.3Ti0.7O3(PHT)铁电薄膜,并对薄膜的微结构和铁电性能进行了表征.通过改变生长条件,对薄膜的微结构和铁电性能进行了初步的研究.实验结果表明,在600℃条件下,直接生长的PHT薄膜主要为非铁电的焦绿石相,结构较差,无自发铁电极化.而在300℃低温自缓冲条件下生长的PHT薄膜为(111)择优取向,半高

稀土正铁氧体RFeO3(R为稀土离子或Y离子)具有正交钙钛矿结构,其B位进行Mn离子掺杂后出现的有趣的磁现象以及磁介电效应引起了人们的广泛关注.2001年Y.Nagata等人对RFe1-xMnxO(3R=Pr,Gd,Dy)的磁性进行了研究,发现Mn离子的引入提高了RFeO3的自旋重取向温度TSR,降低了奈尔温度TN[1].文中从理论上还预言了此类化合物自旋重取向转变温度消失的临界点为Mn离子的掺杂
