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

The patent by Applied Materials Inc. describes multilayered semiconductor particles, or 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 antioxidant properties of the phosphorous-containing material are highlighted, with specific materials listed for use in the particles.

Furthermore, the patent details a method for fabricating displays using these multilayered semiconductor particles, particularly in creating a photoluminescent region with blue quantum dot material. The method involves handling the particles in the presence of oxygen or ambient white light during fabrication operations. The particles are designed with specific layers and materials to enhance their performance in generating light for displays, emphasizing their small size and antioxidant properties for improved efficiency and longevity in display applications.
