Abstract:
A gas discharge lamp has a gas discharge vessel filled with a gas filling suitable for a gas discharge which emits VUV radiation, with a phosphor coating containing a downconversion phosphor. The downconversion phosphor has, in a host lattice, a pair of activators of a first lanthanoid ion and a second lanthanoid ion; a sensitizer selected from the group formed by the thallium(I) ion, lead(II) ion and bismuth(III) ion; and samarium(II) ion co-activator.
Abstract:
An optical signal processing device equipped with a source of electromagnetic radiation of variable intensity, a non-linear optical component, which comprises at least one photoluminescent carbon nanotube, and with a means of detecting electromagnetic radiation utilizes the non-linearity of the photoluminescence of carbon nanotubes for optical signal processing. The invention also relates to a non-linear optical component.
Abstract:
The present invention relates to the use of carbon nanotubes as a substrate for chemical or biological analysis. The invention further relates to the use of this material in separation adherence and detection of chemical of biological samples. Carbon nanotubes are envisaged as surface material of a fixed substrate or in suspension and applications include but are not limited to processes which involve desorption-ionization of a sample, more specifically mass spectroscopy.
Abstract:
This invention concerns the application of inorganic luminescent nanoscale particles, which exhibit optical transitions in the visible spectral range, which can be exploited for excitation purposes and which show an emission band or lines in the NIR range, preferably between 650 and 1100 nm. These nanoscale particles are eventually coated by SiO 2 or other inert oxides, e.g. Al2O3, in order to decrease toxicity and to enhance particle lifetime in living systems.
Abstract:
The invention relates to a white emitting light source with an improved luminescent material of the formula (AEN2/3)*b (MN)*c (SiN4/3)*d1 CeO3/2*d2 EuO*x SiO2*y AlO3/2 wherein AE is an alkaline earth metal chosen of the group of Ca, Mg, Sr and Ba or mixtures thereofand M is a trivalent element chosen of the group of Al, B, Ga, Sc withd1> 10* d2. In combination with a UV to blue light generating device this material leads to an improved light quality and stability, especially an improved temperature stability for a wide range of applications.

Abstract:
The present invention relates to the use of composites or compositions of diamond/non-diamond material, e.g. diamond/non-diamond carbon material for chemical or biological analysis. The invention further relates to the use of this material in separation adherence and detection of chemical of biological samples. Applications of either structurized substrates or mixed phase particles of this material include but are not limited to processes which involve desorption-ionization of a sample, more specifically mass spectroscopy.
