| 英文摘要 | Luminescent materials have wide application prospects in many fields, and hence they have drawn increasing attention. In this work, carbon dots(g-CDs) and polyacrylate sodium(PAAS) were used as raw materials. By combining g-CDs aqueous solution with PAAS, a luminescent composites(g-CDs@PAAS) was obtained. Because the PAAS has a large number of carboxyl group and strong water imbibition thereof, while there are lots of carboxyl, hydroxyl and amino groups on g-CDs surface, leading to the combination of PAAS with g-CDs through hydrogen bonding interaction. In the as-prepared composites, g-CDs maintain monodisperse, which effectively overcomes the aggregation-induced solid-state luminescence quenching of g-CDs. This synthetic method is simple to operate and has no loss of raw materials during the preparation. The loading g-CDs fraction in g-CDs@PAAS is up to 30%, and its photoluminescence quantum yields could achieve 52%. In addition, the g-CDs@PAAS composites have good thermal stability, photostability, and organic solvent resistance. These advantages ensure that g-CDs@PAAS composites can be used as the color conversion layer in the manufacturing of white light-emitting diode. 2019, Higher Education Press. All right reserved. |
