Application: Photoluminescent materials with phosphorous additives to reduce photodegradation (Patent ID: US20230348778A1)

The patent by Applied Materials Inc. describes multilayered semiconductor particles, specifically quantum dots, with a zinc-containing core, zinc-and-selenium-containing inner shell, zinc-containing outer shell, and a phosphorous-containing material like TIPP or B PEDP. These particles are characterized by a size of less than 4 nm and are designed for use in pixel structures, particularly in a photoluminescent region of a light emitting diode structure to generate light with a peak emission wavelength greater than 350 nm. The inclusion of an antioxidant, such as phosphorous with a boiling point above 100°C, enhances the performance of the pixel structure.

Furthermore, the patent details a method for fabricating a display using these multilayered semiconductor particles, involving the formation of a light emitting diode structure, a photoluminescent region, and the incorporation of the quantum dot material with the antioxidant. The method emphasizes handling the photoluminescent material in the presence of oxygen or ambient white light during fabrication. Overall, the patent focuses on the development and application of these specialized semiconductor particles in pixel structures to improve the efficiency and performance of displays, particularly in generating specific wavelengths of light for enhanced visual output.
