Covalent linking of quantum dots to polymer for inorganic-inorganic luminescence films via layer-by-layer assembly with clay

Herein, positively charged QDs were initially prepared by covalently linking to poly(allylamine hydrochloride) (PAH). The resulting PAH-modified QDs in conjunction with MMT nanosheets were utilized to fabricate QDs/MMT UTFs via LBL assembly. Strong photoluminescence, temperature responsiveness, long-term stability and high uniformity make these films potential candidates for a wide range of applications.
