Abstract

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.
