Fully RoHS Compliant Infrared Light Emitting Diodes Based on Novel Lead-free Quantum Dots
Infrared light-emitting diodes (IR-LEDs) technology serves a wide range of applications, including fiber-optic communication, biomedical imaging, security, and night vision. Despite the significant potential of lead-containing colloidal semiconductor quantum dots in advancing IR-LED technology due to their cost-effectiveness and distinct optical properties, their development is significantly hindered by the toxicity of lead. The EU-funded INFLED project addressed the need for novel and efficient lead-free quantum dots. This was crucial as traditional quantum dots often contained heavy metals, posing environmental and health risks. The project was significant for society as it aimed to develop highly efficient, heavy metal-free infrared LEDs, which could lead to safer and more sustainable lighting technologies. Overall, the project's objectives included pioneering a novel synthesis technique and employing rational nanoengineering in both material and device levels, ultimately contributing to cleaner and more efficient lighting solutions.

Project objective
Infrared light-emitting diodes (IR-LEDs) serve a broad range of applications including fiber-optic communications, night vision as well as clinical diagnosis and biomedical imaging. Within the family of nanomaterials, colloidal semiconductor quantum dots (QDs) offer exceptional promises for IR-LEDs due to their unique optical properties and low-cost solution-processability. So far, state-of-the-art QD IR-LEDs are based on lead-containing QDs, which has been severely restricted by the environmental directives e.g. EU’s “Restriction of Hazardous Substances” (RoHS). In fact, current challenges of IR-LED technology are to identify and develop novel and efficient lead-free QDs. INFLED aims at demonstrating the first RoHS-compliant and efficient QD IR-LED based on innovative and environmentally friendly material design and device engineering. The project targets the most efficient heavy metal-free infrared QD using a novel synthesis technique as well as rationally nanoengineering at material level. Furthermore, the resultant design at device level will lead to low trap state density, high solid-state quantum efficiency and thereby efficient LEDs. Hence, the key objectives of this proposal are: i) a novel QD synthesis method; ii) material design at nanocrystalline level; iii) LED device engineering at supra-nanocrystalline level. INFLED is at the crossroad of chemistry, physics and engineering, and therefore is expected to attract significant attention from different disciplines along with offering new insights toward next-generation infrared and quantum network technology.
