摘要
本论文以NH4BF4作为氟源,在葡萄糖基三嵌段共聚物(PAG-b-PNIPAM-b-PAA, PGNA),即聚(丙烯酰基呋喃葡萄糖)–聚(氮–异丙基丙烯酰胺)–聚(丙烯酸)的辅助下,通过简单、温和的湿化学法合成了分散性良好的EuF3微米球。研究发现,该微米球是由薄的纳米片自组装而成,PGNA在自组装过程中既是配体又是分散剂。与EuF3纳米片相比,EuF3微米球表现出更强的荧光性质。
Employing NH4BF4 as fluoride, a simple and mild wet chemical route was adopted to fabricate well-dispersed EuF3 microspheres with the aid of glucosyl triblock copolymer, poly (acryloyl glucofuranose)-block-poly (N-isopropyl acrylamide)-block-poly (acrylic acid) (PAG-b-PNIPAM-b-PAA, PGNA). It was found that the EuF3 microspheres were self-assembled by thin nanodisks and PGNA was used as complexing agent and dispersing stabilizer in self-assembly process. Compared with EuF3 nanodisks, the EuF3microspheres exhibited improved photoluminescent properties.
