Qd hydrogel, qd patterning method, and qd transfer printing method

Abstract

The present invention teaches a QD hydrogel, a QD patterning method, and a QD transfer printing method. The QD transfer printing method includes the following steps. Step 10: forming a QD hydrogel by loading QD material in a hydrogel material capable of resisting high temperature; step 20: forming a film of the QD hydrogel on a metallic substrate; and step 30: covering the QD hydrogel film by a patterning mold conducting nano imprinting, and obtaining a patterned QD hydrogel film. The hydrogel of the present invention has a lower cost and a high utilization, and is appropriate for industrial production. The QD hydrogel of the present invention guarantees a maximum coverage for QD surface ligand and lowers the QD fluorescence loss in the manufacturing process. When applied to a QD CF sheet, its fluorescent efficiency may be enhanced.
