Magnetically adjusting color-converting materials within a matrix and associated devices, systems, and methods

摘要

Magnetically adjusting color-converting particles within a matrix and associated devices, systems, and methods are disclosed herein. A magnetic-adjustment process can include applying a magnetic field to a mixture including a non-solid matrix and a plurality of color-converting particles (e.g. magnetically anisotropic color-converting particles). The magnetic field can cause the plurality of color-converting particles to move into a generally non-random alignment (e.g., a generally non-random magnetic alignment and/or a generally non-random shape alignment) within the non-solid matrix. The non-solid matrix then can be solidified to form a solid matrix. A magnetic-adjustment process can be performed in conjunction with testing and/or product binning of solid-state radiation transducer devices. For example, a position, direction, strength, or duration of a magnetic field used to perform a magnetic-adjustment process can be controlled according to optical output collected from a solid-state radiation transducer device. Measuring the optical output and performing the magnetic-adjustment process can be at least partially concurrent.

1. A method, comprising:
applying a first magnetic field to a first mixture that includes a first non-solid matrix and color-converting particles within the first matrix, so that the color-converting particles within the first matrix move into a first non-random alignment within the first matrix, the first mixture forming a portion of a device; increasing a solidity of the first matrix after the color-converting particles within the first matrix move into the first non-random alignment; adding a second mixture to the device after increasing the solidity of the first matrix, the second mixture including a second non-solid matrix and color-converting particles within the second matrix; and applying a second magnetic field to the second mixture so that the color-converting particles within the second matrix move into a second non-random alignment within the second matrix.
