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.

Hybrid material for optoelectronic applications

The invention relates to the use of specific organopolysilazanes as an encapsulation material for light emitting diodes (LED). The organopolysilazane polymers act as insulating filling materials and are stable over temperature and over exposure to ambient UV radiation. The encapsulating material has good thermal stability against discoloration to yellow by aging even at high temperatures which is a key factor for the long lifetime of an LED encapsulant and the LED performance.

Encapsulation material for light emitting diodes

The invention relates to a plastic film with an interference multilayer system applied thereon that comprises at least two layers. Said layers can be obtained by hardening and/or applying thermal treatment to a coating composition containing nanoscale inorganic solid particles having polymerizable and/or polycondensable organic surface groups, thereby forming a layer that is crosslinked by means of the polymerizable and/or polycondensable organic surface groups. The films can be used as an optical laminating film.

Plastic film with a multilayered interference coating

The invention relates to an alternative composite mask that is substantially composed of a transparent support film coated with a transparent polymer matrix that contains light-absorbing pigment particles or metal particles having an average particle size dranging between 0.5 and 10 &#x3bc;m.

Nanocomposite material for the production of index of refraction gradient films

The invention relates to a method for microstructuring electronic components, which yields high resolutions (&#x2266;200 nm) at a good aspect ratio while being significantly less expensive than photolithographic methods. The inventive method comprises the following steps: i) a planar unhardened sol film of a nanocomposite composition according to claimis produced; ii) a target substrate consisting of a bottom coat (b) and a support (c) is produced; iii) sol film material obtained in step i) is applied to the bottom coat (b) obtained in step ii) by means of a microstructured transfer embossing stamp; iv) the applied sol film material is hardened; v) the transfer embossing stamp is separated, whereby an embossed microstructure is obtained as a top coat (a). The method for producing a microstructured semiconductor material comprises the following additional steps: vi) the remaining layer of the nanocomposite sol film is plasma etched, preferably with CHF/Oplasma; vii) the bottom coat is plasma etched, preferably with Oplasma; viii) the semiconductor material is etched or the semiconductor material is doped in the etched areas.
