1. Light-Emitting Diodes (LEDs): PQDs are used in LEDs due to their high color purity and tunable emission. They offer the potential for creating displays with better color accuracy and energy efficiency. 2. Solar Cells: In photovoltaic applications, PQDs can serve as light absorbers, enhancing the efficiency of solar cells due to their broad absorption spectra and high charge-carrier mobility. 3. Photodetectors: PQDs are employed in photodetectors for their high sensitivity and fast response times, making them suitable for applications in imaging and sensing. 4. Lasers: The narrow emission linewidths of PQDs make them ideal candidates for laser applications, where precise wavelength control is crucial.
