(Invited) Recent Advancements in the Development of Semiconductor Quantum Dots for Solid-State Light Emitting Diodes and Photovoltaic Devices

Abstract

Semiconductor quantum dots (QDs) have emerged as a promising class of nanomaterials with diverse applications in areas such as lighting, displays, photo-detectors, and image sensing. The successful commercialization of QD-based displays, exemplified by QLED TVs, demonstrates the technology's market viability. Ongoing research on QD color down-converters for mini-LED and micro-LED technologies, as well as electroluminescent QD devices, holds considerable promise for advancing future lighting and display technologies. Additionally, QDs have exhibited potential in photovoltaic applications, including photo-detectors and image sensors. This presentation will report our recent progress and developments in QD technology, with a particular emphasis on mini/micro-LED, electroluminescent devices, and photovoltaic applications. We will discuss advancements in QD synthesis and device fabrication, while addressing current challenges and exploring potential future research directions. The report shall provide a comprehensive overview of the current state of QD technology in practical applications and its potential to revolutionize the field of solid-state emission and photovoltaic including up-conversion devices.
