Nanocomposites of Quantum Dots in Polymer Matrices, and Method of Making Same
Invention Summary
Quantum dots (QDs) have become essential for various advanced technologies due to their superior optical and electronic properties. However, conventional methods struggle with uniform dispersion of QDs within polymer matrices, which hinders their effectiveness. This technology presents a novel method for in situ synthesis of quantum dots and nanoparticles within polymer or network solid matrices. The process involves the simultaneous pyrolysis and photolysis of an organometallic precursor with a matrix precursor, creating a complete material where QDs are uniformly dispersed. The QDs' size, band gap energy, and spatial distribution can be finely tuned, allowing for customization of the material's physical properties to suit specific applications.
Benefits
- Uniform Dispersion-Achieves a more uniform distribution of QDs within matrices, leading to improved material properties.
- Customizable Properties-Ability to tailor nanoparticle size and band gap energy for specific needs, enhancing the performance of the final product.
- Versatile Application-Suitable for various electronic devices, including photovoltaic cells, displays, and sensors.
- Efficient Production-Streamlines the production process by synthesizing QDs and incorporating them into matrices in a single step.
