摘要:
The invention relates to a method for providing a utensil with a decoration by means of an optical interference grating. The utensil is provided with a sol-gel precursor which is embossed with a flexible stamp to create an optical interference grating. The interference grating can be provided with a second precursor of a material with an index of refraction higher than that of the sol-gel layer, and provided with a transparent, non-scattering topcoat. The invention further relates to an appliance, e.g. an iron or a shaver, coated with an organosilane layer provided with an optical interference grating.

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.
摘要:
The invention pertains to a composition comprising silver metal particles and an additive, characterized in that the additive is a silane derivative comprising at least one methyl group and at least one alkoxy group. Preferably, the silane derivate is methyl trimethoxysilane, methyl triethoxysilane, or a mixture thereof. The compositions can be used to make thermal resistant conductive silver-containing layers, for instance for use in AMLCD.
