[Eu(Bipy)2]Cl3和[Tb(Bipy)2]Cl3在有机功能化剥层水滑石表面上的组装及光致发光性质
Assembly of Rare-earth Complex [Eu (Bipy) 2] Cl3 and [Tb (Bipy) 2] Cl3 on Surface Modified Exfoliated LDHs and Photoluminescent Properties of the Assemblies
摘要
Abstract
[Eu (Bipy) 2] Cl3 and [Tb (Bipy) 2] Cl3 are assembled on surface of exfoliated Mg2Al-NO3-LDH modified with N-[3-(triethoxysily) propyl]-acetamide by covalent bonding and photophysical properties of the assembly were studied.Emission spectra show that the fluorescence intensities of the rare earth complexes are increased on the surface of exfoliated Mg2Al-NO3-LDH greatly.The fluorescence intensities of EM-Mg2Al-NO3-LDH/[Eu (Bipy) 2] 3+ and EM-Mg2Al-NO3-LDH/[Tb (Bipy) 2] 3+ are 43.5 and 53.7 times of the pure compelex.XPS and UV-Vis studies show that the increase is illuminated from the interactions between the host and guests,and the affections from host' s structure to the luminance of guests were studied carefully.关键词
