QUANTUM DOT, COMPOSITION INCLUDING QUANTUM DOT, QUANTUM DOT COMPOSITE, DISPLAY PANEL, AND ELECTRONIC DEVICE INCLUDING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17903242 titled 'QUANTUM DOT, COMPOSITION INCLUDING QUANTUM DOT, QUANTUM DOT COMPOSITE, DISPLAY PANEL, AND ELECTRONIC DEVICE INCLUDING SAME

Simplified Explanation

The patent application describes a quantum dot that consists of a core made of a semiconductor nanocrystal and a shell made of another semiconductor nanocrystal. The quantum dot contains indium, zinc, phosphorus, and sulfur, but does not contain cadmium. It has a specific optical density for a certain wavelength range and emission peak wavelength, and the core volume is within a certain range.

• The quantum dot is made up of a core and a shell, both made of different semiconductor nanocrystals.
• The quantum dot does not contain cadmium, which is a toxic material.
• The quantum dot has a specific optical density for a certain wavelength range and emission peak wavelength.
• The core volume of the quantum dot falls within a specific range.

Potential Applications

• Biological imaging and labeling: Quantum dots can be used as fluorescent probes in biological imaging to track and study cellular processes.
• Display technology: Quantum dots can be used in displays to enhance color reproduction and improve energy efficiency.
• Photovoltaics: Quantum dots can be used in solar cells to improve their efficiency and performance.

Problems Solved
