摘要

采用微波-超声协同法

在不同反应时间下制得了相对结晶度好、颗粒尺寸均一、形貌规则的稀土有机配合物Sm(TTA)

Phen.采用红外光谱仪、X射线衍射仪、场发射扫描电镜、荧光光谱仪对配合物进行了性能表征

并讨论了反应时间对其相对结晶度、粉体颗粒形貌尺寸、荧光性能的影响及其相互关系.结果表明:采用微波超声法反应能得到结晶度较好的Sm(TTA)

Phen配合物.最佳反应时间为4 h

此时可得到形貌规则、尺寸均一(约为5 m)的三斜相厚片状的配合物粉体

具有较高的相对结晶度(约为72%)且荧光强度较高.在放置90 d后

样品溶液的荧光强度有所下降

且相对结晶度较高的样品荧光衰减较小.

Abstract

Highly crystallized Sm(TTA)

Phen with small size and uniform morphology was prepared by a rapid and efficient microwave-ultrasound technology. Frontier FT-IR/FIR spectrometer (FT-IR)

X-ray diffraction (XRD)

field emission scanning electron microscopy (FSEM)

and photoluminescence (PL) spectra were employed to characterize the samples. The relationships among reaction time

relative crystallinity

particle morphology and fluorescence properties were discussed. The results indicate that the highly crystalline Sm(TTA)

Phen can be successfully synthesized by microwave-ultrasound method. The optimum reaction time is 4 h for typical triclinic crystal powder with size of 5 m

which has 72% highly-crystalline and good luminescence property. When the samples were tested after 90 d

the fluorescence decayed. The higher the crystallinity is

the less fluorescence decreases.
