Synthesis and thermal stability of Sm(p-FBA) Phen Luminescent complex

摘要

Sm(p-FBA) Phen complex have been synthesized by wet chemical method.People study the thermal stability in the application.They were characterized using Fourier Transform Infrared (FT-IR) spectroscopy and fluorescence spectroscopy.The thermal stability of complex was analyzed by TG-DSC.The results shows the Sm(p-FBA) Phen complex is stable below 310°C.The photoluminescence (PL) analyses exhibit that the complex emits the characteristic red fluorescence of Sm (Ⅲ) ions at 644 nm under ultraviolet light excitation.The highest peak of Sm(p-FBA) Phen fluorescence intensity only declined 41％ after heat treatment 280°C.The morphology of the comlplex with diameter of 100 ± 50 nm nm is characterized by Scanning Electron Microscopy (SEM).
