Abstract: 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.

Abstract: A white light source (1) comprising an array of at least one blue light source (2), at least one green light source (3), and at least one red light source (4) is disclosed. The blue light source (2) comprises a first light emitting diode (2?) capable of emitting light at a first wavelength. A first wavelength-converting material (2?) is arranged to absorb at least a portion of the light of the first wavelength, and the first wavelength-converting material (2?) is capable of emitting light at a second wavelength, which is at least 500 nm.

Abstract: A display device (100) comprising a plurality of lighting units (101), each lighting unit comprising at least one light emitting diode (202) being provided with a fluorescent element (203) arranged to absorb at least part of the light emitted by said light emitting diode and emit light of a wavelength range different from that of the absorbed light is provided. The fluorescent element (203) comprises at least one phosphor being an europium(II)-activated halogeno-oxonitridosilicate of the general formula EaxSiyN2/3x+4/3y:EuzOaXb.

Abstract: 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.

Abstract: 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.
