研究目的
Investigating the enhancement of optical properties of quantum dot films through the fabrication of micro-dimple/pillar arrays using a track-etching mold.
研究成果
The track-etching mold method effectively enhances the optical properties of quantum dot films, with a 12.06% improvement in haze for MPS-PDMS films and a 7.7% increase in red optical power for MDS-QDs films. This approach offers a simple and efficient alternative to traditional imprinting techniques.
研究不足
The study does not explore the scalability of the fabrication process for industrial applications or the long-term stability of the fabricated films under operational conditions.
1：Experimental Design and Method Selection:
The study employs a track-etching mold prepared by bombarding a polycarbonate film with high-speed particles to create a microporous structure. This mold is then used to transfer micro-dimple/pillar arrays onto PDMS and quantum dot films.
2：Sample Selection and Data Sources:
Red CdSe/ZnS quantum dots are used for their high luminous efficiency and stability.
3：List of Experimental Equipment and Materials:
Polycarbonate film, PDMS, curing agent, CdSe/ZnS quantum dots, n-hexane, OE6650 B gel, OE6650A gel.
4：Experimental Procedures and Operational Workflow:
The process involves creating a microporous PC film, transferring the structure to PDMS to form MPS-PDMS film, and then using this film to fabricate MDS-QDs film.
5：Data Analysis Methods:
Optical performance is measured in terms of haze, reflectivity, absorption rate, and fluorescence properties.
