Covalent and noncovalent cascade strategy for enhancing QY of red-emitting, carbon dot-based composites

Key Points

• The quantum yield of red-emitting carbon dots significantly increases with the cascade strategy, enhancing overall performance.
• A notable improvement in quantum yield by a factor of at least two is observed, indicating successful modification of composite materials.
• The observational analysis focuses on the interaction of covalent and noncovalent bonding in carbon dot-based composites, improving their optical properties.
• This approach may enable enhanced applications in lighting and displays, highlighting the importance of emission enhancement in luminous materials.
