What are the Advantages of Core Shell Quantum Dots?
The core shell structure offers several advantages over traditional quantum dots:
1. Enhanced Stability: The shell protects the core from oxidation and other environmental factors. 2. Improved Quantum Yield: The shell reduces non-radiative recombination, leading to brighter emission. 3. Tunable Emission: By varying the size and composition of the core and shell, the emission wavelength can be precisely controlled. 4. Reduced Toxicity: Using non-toxic materials for the shell can reduce the overall toxicity of the quantum dots, making them safer for biomedical applications.
