Despite their promising applications, quantum dots face several challenges:
Toxicity: Many quantum dots contain heavy metals like cadmium, which are toxic and pose environmental and health risks. Stability: Ensuring the long-term stability of quantum dots in different environments remains a technical challenge. Scalability: Producing high-quality quantum dots on a large scale at a reasonable cost is still difficult. Integration: Integrating quantum dots into existing commercial devices and systems requires more research and development.
