选用甲基苯骈三氮唑(TTA)作为Eu3+络合物的第一配体,探究了在乙醇溶液体系与水溶液体系两个不同条件下,第二配体及表面活性剂对体系荧光强度的影响。两个体系分别选择了三乙胺、邻菲咯啉(phen)作为第二配体,邻非咯啉(phen)、曲拉通-100(TX-100)作为表面活性剂,在乙醇体系下,Eu3+:TTA:三乙胺:phen的最佳比例为1:3:10:1,在水溶液体系下,Eu3+:TTA:phen:TX-100的最佳比例为1:5:1:5,最后分别将两种络合物使用掺杂法制备了聚氯乙烯(PVC)薄膜,通过荧光光谱测试,得到的两种薄膜均可将紫外光转换为可被植物吸收利用的可见光。
Methylbenzotriazole (TTA) was chosen as the first ligand of Eu3 + complex. The effects of the second ligand and surfactant on the fluorescence intensity of the system were investigated under two different conditions: ethanol solution system and aqueous solution system influences. Two systems were selected triethylamine, phenanthroline (phen) as the second ligand, adjacent to non-phenine (phen), Triton -100 (TX-100) as a surfactant in the ethanol system , The optimal ratio of Eu3 +: TTA: triethylamine: phen is 1: 3: 10: 1, and the optimal ratio of Eu3 +: TTA: phen: TX-100 is 1: 5: 1: 5 in aqueous solution. At last, polyvinyl chloride (PVC) films were prepared by doping the two complexes respectively. Both of them were converted into visible light which can be absorbed and utilized by plants through the fluorescence spectroscopy test.
