Abstract: The composition of articles can be identified using luminescent codes printed or coated onto the articles (or labels on the articles) by means of an ink which contains long persistence luminescent materials. Radiation is used to excite the luminescent materials and this is then extinguished before the article passes beneath a spectrometer. An infrared beam then strikes the article in order to stimulate emission from the long persistence luminescent materials, via a detrapping mechanism, and the spectrometer detects the emission in order to identify the article.

Abstract: There is herein described a structure for converting light from LED arrays from shorter wavelength, for example blue, into longer wavelength light, for example red and green, so as to form displays containing red, green and blue sub-pixels. More particularly, the present invention relates to a structure and process in which light from LED arrays of the same wavelength is converted into alternate colours by means of a colour conversion structure.

Abstract: There are disclosed plastics materials (110; 520; 640) that include one or more phosphors (210) for absorbing ultraviolet (UV) light (170, 420) and re-radiating (160, 410) the light at a longer wavelength, for example the red wavelengths at 680 nm and 700 nm used by a plant (130) for photosynthesis. Such plastics materials may be used to protect the plastic (110, 500) from UV-induced degradation. In another embodiment, a light source (600) is provided with an encapsulant (640) that contains a phosphor (210) to prevent UV-light from escaping from the light source. Examples of the phosphor (210) are iron activated lithium aluminate phosphor although the phosphor may be based on lattices comprising, for example, aluminates, silicates, aluminosilicates, phosphates or borates or mixtures thereof. The phosphors may include activators/co-activators/sensitizers based on transition metals or lanthanides.

Abstract: There is disclosed an electroluminescent device (200; 300; 400; 500) in which a phosphor (6) is deposited in gaps (3) between electrodes (2a, 2b). The deposition of phosphor on top of the electrodes is minimised as phosphor on top of the centre of an electrode will not experience a significant electrical field and thus will not usefully emit light. Some embodiments improve the efficiency with which phosphor is utilised during manufacture. In some embodiments (400; 500) the electrodes and phosphor may be on opposite sides of a substrate (1). In some embodiments (100), the phosphor has a sufficiently high dielectric strength that a dielectric layer between the phosphor and the electrodes is not required.

Abstract: A phosphor layer for an electroluminescent panel comprises a phosphor powder held in a binder. The binder comprises a mixture of two constituents, one of which is a drying oil or a semi-drying oil or a derivative and the other constituent is a sol-gel precursors. Examples of suitable oils are linseed oil, grape seed oil, sunflower oil and soybean oil. Examples of suitable sol-gel precursors are tetraethyl orthosilicate, boron iso-propoxide, aluminium sec-butoxide titanium iso-propoxide. Metal salts such as metal alkoxides, metal acetates and metal nitrates may be mixed with the sol-gel precursors.

Abstract: I have invented a device, which will introduce ozone into the combustion chambers of all internal combustion engines by passing ambient air through the intake manifold and between the electrodes of a high voltage silent discharge, where the oxygen with two atoms is thereby, instantaneously converted to ozone, providing rapid and complete combustion from the added fifty percent more oxygen by weight and volume, providing greater power and efficiency and practically eliminating the need for a catalytic converter to eliminate pollution.
