Abstract

The present disclosure provides a photosensitive resin composition and a method for forming a quantum dot pattern using the same. The photosensitive resin composition includes quantum dots which are dispersed in the photosensitive resin composition and each has a modification layer. The method for forming a quantum dot pattern includes coating, exposing and developing a photoresist to obtain the quantum dot pattern, wherein the photoresist is the above-mentioned photosensitive resin composition.

Description

technical field [0001] The invention relates to a photosensitive resin composition and a method for preparing quantum dot patterns with the photosensitive resin composition. Background technique [0002] Quantum dots, also known as semiconductor nanocrystals, are a new type of semiconductor nanomaterial with a size of 1-10nm. They have unique photoluminescence (EL) and electroluminescence (PL) properties due to quantum size effects and dielectric confinement effects. Compared with traditional organic fluorescent dyes, quantum dots have high quantum yield, high photochemical stability, not easy to photolysis, wide excitation, narrow emission, high color purity, luminous color can be adjusted by controlling the size of quantum dots, etc. optical properties. Therefore, the application of quantum dots in display, lighting, solar cells, biomarkers and other fields has become a research hotspot all over the world. [0003] In the field of display, quantum dots (as EL and PL) ha...
