SYSTEMS AND METHODS FOR DEPOSITING PHOSPHOR CONTAINING INK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18502765 titled 'SYSTEMS AND METHODS FOR DEPOSITING PHOSPHOR CONTAINING INK

Simplified Explanation

The patent application discloses phosphor materials and devices containing such phosphor materials. The ink composition includes a Mn4+ doped phosphor of formula A[MF]:Mn (I) and at least one rare earth containing Garnet phosphor, with the rare earth Garnet phosphor present in the phosphor material in an amount of at least about 80 wt% based on the weight of the phosphor material.

• Mn4+ doped phosphor of formula A[MF]:Mn (I) is a key component of the ink composition.
• The ink composition also includes at least one rare earth containing Garnet phosphor with a specific particle size range.
• A, M, x, and y in the formula represent specific elements and values.

Potential Applications

This technology could be used in:

• LED lighting
• Display screens
• Medical imaging devices

Problems Solved

• Enhanced brightness and color rendering in lighting applications
• Improved efficiency in display screens
• Better image quality in medical imaging devices

Benefits

• Higher performance compared to traditional phosphor materials
• Increased energy efficiency
• Improved overall user experience

Potential Commercial Applications

Optimizing phosphor materials for:

• Consumer electronics
