The present invention relates to a process for manufacturing an optoelectronic device, wherein a layer of a formulation containing a silazane polymer and a wavelength converting material is applied to an optoelectronic device precursor, precured by exposure to radiation and then cured. There is further provided an optoelectronic device, preferably a light emitting device (LED) or a micro-light emitting device (micro-LED), which is prepared by said manufacturing process.

Manufacturing process for an optoelectronic device

The present invention relates to a manufacturing method for a wavelength converting component which is prepared from a dispersion containing a crosslinkable ceramizable polymer material having a silazane repeating unit and at least one wavelength converting material. There are further provided wavelength converting components which can be used for converting blue, violet and/or UV light into light with a longer wavelength. There is also provided a light source and a lighting unit comprising said wavelength converting components.

Wavelength converting component

The present invention relates to silazane-siloxane random copolymers as well as their production and their uses, particularly in LEDs.

Silazane-siloxane random copolymers, their production and use

The present invention relates to a formulation suitable for the preparation of a highly refractive encapsulation material with good barrier properties towards water vapor for an LED, to an encapsulation material for an LED having a high refractive index and good barrier properties towards water vapor which is obtainable from said formulation and to a light emitting device (LED) comprising said encapsulation material. The formulation comprises a polymer comprising a first repeating unit Uand a second repeating unit U; and a surface-modified nanoparticle, wherein the surface-modified nanoparticle does not contain any zirconium dioxide.

Formulation for an LED encapsulation material

The present invention relates to a formulation suitable for the preparation of a highly refractive encapsulation material with good barrier properties towards water vapor for an LED, to an encapsulation material for an LED having a high refractive index and good barrier properties towards water vapor which is obtainable from said formulation and to a light emitting device (LED) comprising said encapsulation material. The formulation comprises a polymer comprising a first repeating unit Mand a second repeating unit M; and a surface-modified zirconium dioxide nanocrystal.

Formulation for LED encapsulation material

The present invention relates to a method for producing silazane-siloxa copolymers and the use of such copolymers, particularly in LEDs.
