Abstract: An electroluminescent device includes a substrate and a laminated body composed of a first electrode, an electroluminescent layer and a second electrode. The light output out of the electroluminescent device is increased by arranging a colloidal layer between the substrate and the laminated body. By using pigments in the colloidal layer, the emission color of the electroluminescent device can be changed and the daylight contrast improved.

Abstract: The invention relates to a plasma screen having a structured black matrix (8) which is coated with a reflecting layer (9) on the side turned away from the viewer. Visible light incident from outside is absorbed by the black matrix (8) and light incident from inside is reflected by the reflecting layer (9). This enhances the LCP value of the whole plasma screen.

Abstract: Color picture screen consists of a picture screen glass, a phosphor layer and a color filter between the picture screen glass and the phosphor layer. The color filter contains dye particles having a diameter of more than 200 nm together with colloidal particles having a diameter of less than 100 nm. An Independent claim is also included for a process for the production of the screen comprising initially depositing a layer of dye particles onto the screen and filling the spaces between the particles with colloidal particles. Preferred Features: The colloidal particles contain SiO2, ZrO2, SnO2, CeO2 or ZnO.

Abstract: The invention relates to a light emitting device (1) with high colour rendering comprising a wavelength converting member (2) with a luminescent medium for wavelength conversion of blue light and/or ultraviolet light (10) into red light and/or yellow and/or green light and a light source (3) emitting blue light (10) and/or ultraviolet light arranged to pump the luminescent medium, said luminescent medium essentially having a main phase of a solid state host material which is doped with Ce3+-ions. According to the invention the host material comprises ions of a further rare-earth material Ln, wherein the host material is selected such that the emission energy of the 5d-4f emission on Ce3+-ions is energetically higher than the absorption energy into an upper 4fn state of the further rare-earth material Ln, and wherein the light emission of wavelength converted light is caused by an intra-atomic 4fn- 4fn transition within the ions of the further rare-earth material. The invention further relates to a corresponding lighting system comprising the light-emitting device and a corresponding luminescent medium.
