Abstract
A method of producing an outcoupling element for an optoelectronic component includes A) providing quantum dots each having a core made of a semiconductor material, B) applying an inorganic or a phosphonate-containing ligand shell on a respective core of the quantum dots, and C) introducing the quantum dots with the ligand shell into a matrix material, wherein introducibility of the quantum dots with the ligand shell is facilitated compared to the quantum dots produced in step A), and the outcoupling element is transparent for radiation from the red and/or IR region.

A method of producing an outcoupling element for an optoelectronic component comprising:
- A) providing quantum dots each having a core made of a semiconductor material,
- B) applying an inorganic or a phosphonate-containing ligand shell on a respective core of the quantum dots, and
- C) introducing the quantum dots with the ligand shell into a matrix material, wherein introducibility of the quantum dots with the ligand shell is facilitated compared to the quantum dots produced in step A), and the outcoupling element is transparent for radiation from the red and/or IR region.
An outcoupling element comprising:
- a matrix material which is a highly refractive silicone and in which quantum dots each having a core of GaP or InP are embedded,
- wherein a respective core has a ligand shell of silica or phenyl-functionalized siloxane-phosphonate, and the outcoupling element is transparent to radiation from the red and/or IR region.
