摘要:
An inorganic phosphor body (102) for a light emitting diode, comprising an inorganic luminescent material is provided. A bonding precursor material (103) is arranged on a surface of said inorganic phosphor body (102), and the bonding precursor material comprises an at least partly hydrolyzed organically modified silane. The attachment of the bonding precursor material to the inorganic phosphor body is separated from the bonding of the inorganic phosphor body to a light emitting diode. Thus, the attachment of the bonding precursor material to the inorganic phosphor body may be performed at conditions detrimental to the LED.

The present invention relates to a light-emitting device comprising at least one light-emitting diode (LED) chip (12), and an inorganic optical element (14) being connected to the chip(s) by means of a bond (16). The light-emitting device is characterized in that the bond is of a bonding material comprising a matrix including silicon and oxygen atoms with hydrocarbon groups directly bonded to at least a fraction of the silicon atoms. Such inorganic-organic bonding material has very high photo and thermal stability. As a result, high power and high lumen LED chips can be deployed, whereby high brightness light-emitting devices can be realized. The present invention also relates to a method for the manufacture of such light-emitting device.

A cooling device for cooling a light-emitting semiconductor device, such as a LED device (20), comprises a ceramic plate (15) having coolant-conveying channels (12) incorporated therein. The ceramic plate (15) is adapted for forming an integral part of the optical system of the light-emitting semiconductor device (20) and to cool a light-emitting portion (26) of the light-emitting semiconductor device (20). A method of forming a cooling device comprises the steps of forming a charge of ceramic particles, embossing the charge with a stamp to form coolant-conveying channels in the charge, hardening the charge, and providing a cover on top of the channels to seal them.

This invention relates to a method for forming a patterned layer on a substrate by means of an imprint process. According to the method a first layer is provided on the substrate, and a pattern of recesses is provided in the first layer by imprinting the layer with a patterning means. Then the first layer is cured. The curing is followed by performing a first surface treatment onto the first layer to make the surface of thereof hydrophilic, and then performing a second surface treatment onto a selected subarea of the surface of the first layer to make the. subarea hydrophobic. The subarea includes surface portions between the recesses and excludes the recesses. Finally, a conducting pattern material (41) is deposited into the recesses.

摘要:
The matching of refractive index of a nanoporous membrane with an analyte solution used with the membrane for use in a sensor is described. Scattering of the excitation and/or emitted light is reduced by matching the refractive indices. This improves efficiency when the porous translucent membrane is used in flow-through or flow-over sensors such as biosensors.
