QUANTUM DOT DEVICE AND QUANTUM DOTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18101603 titled 'QUANTUM DOT DEVICE AND QUANTUM DOTS
Simplified Explanation
The patent application is about quantum dots and electroluminescent devices that use these quantum dots. The quantum dots have a core made of a semiconductor nanocrystal called zinc chalcogenide, and a shell made of zinc, sulfur, and selenium. The average size of the quantum dots is larger than 10 nm. These quantum dots do not contain cadmium and emit light in a specific wavelength range of 430 nm to 470 nm.
- Quantum dots are used in electroluminescent devices.
- The quantum dots have a core made of zinc chalcogenide and a shell made of zinc, sulfur, and selenium.
- The average size of the quantum dots is larger than 10 nm.
- These quantum dots do not contain cadmium.
- The quantum dots emit light in the wavelength range of 430 nm to 470 nm.
Potential Applications
- Display technology: Quantum dots can be used in displays to enhance color accuracy and brightness.
- Lighting: Quantum dots can be used in LED lighting to improve energy efficiency and color quality.
- Solar cells: Quantum dots can be used in solar cells to enhance light absorption and increase efficiency.
Problems Solved
- Elimination of cadmium: The use of quantum dots without cadmium reduces the environmental impact and potential health risks associated with cadmium-based quantum dots.
- Improved performance: The specific composition and size of the quantum dots result in improved light emission and efficiency in electroluminescent devices.
Benefits
- Enhanced color accuracy: The use of quantum dots in displays and lighting can result in more vibrant and accurate colors.
- Energy efficiency: Quantum dots can improve the energy efficiency of LED lighting and solar cells.
- Environmental friendliness: The absence of cadmium in the quantum dots reduces the environmental impact of their use.
