A phosphor combination may include a first phosphor and a second phosphor. The second phosphor may be a red-emitting quantum dot phosphor. The phosphor combination may optionally include a third phosphor that is a red-emitting phosphor with the formula (MB) (TA)3-2x(TC)1+2xO4-4xN4x:E. A conversion element may include the phosphor combination. An optoelectronic device may include the phosphor combination and a radiation-emitting semiconductor chip.

Luminophore combination, conversion element, and optoelectronic device

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.
