摘要
以铕(Ⅲ)氯化物、乙酰丙酮、2,2联吡啶为原料合成了Eu(Caac)3BIPY配合物,用元素分析、红外、紫外-可见对它进行表征,然后将配合物掺杂到低密度聚乙烯的四氢呋喃(THF)溶液中,制备光致发光聚乙烯膜,研究了它的红外光谱,紫外光谱及荧光性质。研究结果表明,铕配合物含量在1.75%时荧光强度最强。
The compound Eu（Caac）3BIPY has been synthesized by the reaction of Eu（Ⅲ）chloride,acetyl acetone and 2,2-bipyridine.The compound was characterized by elemental analysis,IR spectrometry and UV spectrometry.The complex was doped with THF solution of low density polyethylene to prepare photoluminescencet polyethylene film.The film was researched by IR spectrometry,UV spectrometry and fluorescence spectrometry.The results showed that fluorescence intensity was strongest,when the content of Eu complex was 1.75%.
