Abstract

A quantum dots material solution is provided. The quantum dots material solution includes a quantum dots material; a ligand chelated to the quantum dots material; a fast material capable of generating, upon a first irradiation, a quencher quenching the quantum dots material; a second material capable of at least partially converting the quantum dots material in a plurality of block regions from a first form into a second form. The quantum dots material in the second form has a lower solubility in a developing solution than the quantum dots material in the first form.
