Light emitting devices (LEDs) are described herein. An LED includes a light emitting semiconductor structure, a wavelength converting material and an off state white material. The light emitting semiconductor structure includes a light-emitting active layer disposed between an n-layer and a p-layer. The wavelength converting material has a first surface adjacent the light emitting semiconductor structure and a second surface opposite the first surface. The off state white material is in direct contact with the second surface of the wavelength converting material and includes multiple core-shell particles disposed in an optically functional material. Each of the core-shell particles includes a core material encased in a polymer or inorganic shell. The core material includes a phase change material.

The invention relates to a method for manufacturing composite particles, particularly composite particles based on titanium dioxide and carbonate, with the help of combined mixing, homogenization and precipitation in a pipeline mixer based on the rotor-stator principle. The method is based on an aqueous suspension of a particulate base component (e.g. titanium dioxide), which is preferably produced in an intermediate vessel equipped with a high-speed agitator. At least one of the required precursor substances and/or a pH-controlling component for precipitating calcium carbonate, for example, is metered into the pipeline mixer, and the calcium carbonate is precipitated. The method can be operated as a continuous process or as a batch process and permits shorter production times. The composite particles produced display homogeneous dispersion of the precipitated particles and the particulate base component.
