摘要:
This invention relates to a new method for the production of nitride-based phosphors, in particular, of phosphors containing rare earth elements. The phosphors can be used, for example, in light sources, especially in Light Emitting Devices (LEDs).
摘要:
The invention relates to a new class of luminescent substances (phosphorous) based on an universally dopable matrix made of an amorphous, at the most partially crystalline network of the elements P, Si, B, Al and N, preferably the composition Si3B3N7. Optical excitation and emission can be varied in this system over the entire practically relevant field by incorporation of any cationic activators, alone or in combination, but also by incorporation of oxygen as anionic component. This opens up the entire spectrum of use of luminescent substances, such as illumination systems or electronic screens.

摘要:
The present invention relates to novel methods for the salt-free polymerization of borosilylamines, which comprise the structural feature Si—N—B and borosilyl hydrocarbons, which comprise the structural feature Si—X—B, wherein X may be a methylene group or a hydrocarbon chain CxHy or a cyclic hydrocarbon unit, by reaction thereof with disilazanes R3Si—NR—SiR3.
摘要:
The present invention relates to a method for producing hydrogen-free carbon nitrides, in particular carbon nitrides of the stoichiometry C3N4. The carbon nitrides are synthesized using hydrogen-free reactants, namely inorganic isocyanates that release only CO2 when thermally treated. In particular, a way of cheaply and efficiently providing carbonitrides, advantageously in the form of powders or coatings, is proposed.
摘要:
The invention relates to a light source comprising a primary radiation source and a luminescent substance, and to a method for producing this light source. The invention relates, in particular, to a method for producing an electric light source using one or more luminescent substances emitting in the visible spectrum range, and at least one primary source emitting preferably in the UV range, and which is preferably, but not exclusively, an LED.
摘要:
The present invention relates to compounds on apatite basis, having the general formula M5 (A04)3X wherein X is situated in the hexagonal channels of the apatite structure and includes Cu-atoms, processes for the preparation thereof as well as applications of these compounds. The compounds presented herein are particularly useful as pigments.
摘要:
The invention relates to a legrest for a wheelchair, provided with a footrest and a calfrest. In a first, supporting position (ready for use), this footrest and calfrest are designed for supporting at least a part of a leg of a user seated during use in the wheelchair. The calfrest can be moved to a non-supporting, second position (ready for transfer), wherein the calfrest is located outside the space which is occupied by the legs of a wheelchair user upon sitting down in and/or rising from the wheelchair. The pivotal direction of the calfrest is then such that the path of travel between said first and second position is located substantially outside the space occupied by the legs of the wheelchair user in the first, supporting position.
