An optoelectronic apparatus is disclosed. In an embodiment, the apparatus includes at least one wavelength conversion region which includes at least one dual emitter as wavelength conversion material, wherein the wavelength conversion region converts primary radiation at least in part into secondary radiation, and wherein the dual emitter includes a first electronic base state and a second electronic base state, together with a first electronically excited state and a second electronically excited state which may be reached from the first electronically excited state. The dual emitter further includes emission proceeding from the second electronically excited state into the second base state.
