Project description
All-III-V colloidal quantum dots enable short-wave infrared emission
Short-wave infrared emitters based on colloidal quantum dots (CQDs) are challenged by energy inefficiency and a reliance on restricted heavy-metal-containing materials. With the support of the Marie Skłodowska-Curie Actions programme, the FLARE project aims to overcome these limitations with compliant, thermally stable III-V semiconductors. Specifically, it aims to develop all-III-V core-shell CQD short-wave infrared emitters in which both the core and the shell are made entirely of III-V semiconductors. Combining novel synthesis routes, the project will produce a library of indium arsenide-based heterostructures with systematically varied properties and conduct quantitative structure-property studies. Proof-of-concept short-wave infrared CQD light-emitting diodes will advance III-V CQDs as a sustainable platform for infrared photonics.
Objective
Short-wave infrared (1100-2500nm) colloidal quantum dot (CQD) emitters remain limited by strong Auger losses and the absence of sustainable, RoHS-compliant material systems. III–V semiconductors offer a promising solution by combining RoHS-compliance and superior thermal stability with the potential for tailored confinement in core–shell architectures. Yet, all-III–V core–shell CQDs have not been realized due to major synthetic challenges. FLARE will address this gap by combining molten-salt and organic-solvent routes to demonstrate graded type-I core–shell CQDs with suppressed Auger losses, emitting in the 1200–1700 nm range. Their technological potential will be validated in proof-of-concept SWIR light-emitting diodes (LEDs). Expected results include new synthetic routes to all-III–V core–shell CQDs, a library of InAs-based heterostructures with systematic variation of core size, shell thickness and composition, quantitative structure–property relationships linking confinement and strain to exciton and biexciton dynamics, and SWIR CQD LEDs with enhanced power outputs. Together, these advances will position III–V CQDs as a sustainable platform for SWIR photonics, bridging the gap to state-of-the-art visible-CQDs while avoiding toxic heavy metals.
