Photoluminescent nanoparticles and their synthesis and uses

Abstract

Disclosed is a method of preparing polymeric photoluminescent dots in water using inexpensive non-conjugated polymers. The resulting polymeric photolumineseent dots display the following properties: excellent water dispersibility, low toxicity, high adsorptivity, good photo-stability and high quantum yield. The photoluminescent properties are not influenced by aggregation- caused quenching effect.The method is amenable to scale-up and is environmentally friendly. 本发明公开了一种使用廉价的非共轭聚合物在水中制备光致发光聚合物纳米颗粒的方法。所得的光致发光聚合物纳米颗粒具有以下特性：优异的水分散性、低毒性、高吸附性、良好的光稳定性和高量子产率。纳米颗粒的荧光性质不受聚集荧光淬灭效应影响。该合成方法适用于大规模生产并且环保。
