Problem Statement

Despite the immense potential of quantum dots (QDs) in revolutionizing various fields, several challenges hinder their full utilization in specific applications. These challenges arise from limitations in our ability to precisely engineer QDs to achieve optimal performance:

  • Tailoring Properties for Specific Needs: While the size, composition, and structure of QDs can be manipulated, achieving the exact combination required for a desired application (e.g., specific emission wavelength for LEDs, high biocompatibility for targeted probes) remains a challenge. Current engineering methods may not offer the necessary precision or control.

  • Balancing Efficiency and Stability: Enhancing one aspect of a QD, such as its light emission efficiency, may come at the cost of stability or vice versa. Finding the right balance between these properties for specific applications requires further research and development of engineering techniques.

  • Scalability for Real-World Implementation: Current methods for synthesizing and engineering QDs often lack the scalability needed for large-scale production. This hinders their widespread adoption in commercially viable technologies like QD-based LEDs or solar cells.

  • Biocompatibility Concerns for Biomedical Applications: While QDs offer immense promise in bioimaging and drug delivery, concerns exist regarding their potential toxicity within living organisms. Engineering biocompatible QDs that are safe for use within the body remains a crucial hurdle.

This project aims to address these limitations by exploring advanced techniques for engineering QDs with a focus on specific applications. By tackling these challenges, we can unlock the true potential of QDs. Also pave the way for significant advancements in optoelectronics, biomedicine, and beyond.
