    摘要: The invention relates to a display screen comprising a phosphor composition of a sulphide and/or selenide-containing phosphor which is provided with a coating which comprises one or more catena-polyphosphates of one or more alkaline earth metals, zinc, cadmium and/or manganese. In such a display screen, in particular a low-energy cathode ray display screen, the advantages of the efficient sulphide or selenide-containing phosphors can be used and said display screen remains bright and rich in contrast for a long period of time because the coating acts as a stabilizing protective coating which limits the corrosion processes in sulphide and/or selenide-containing phosphors induced by low-energy radiation.

A light-emitting diode as a radiation source is especially contemplated. The invention also relates to a red to amber yellow emitting europium(III)-activated phosphor comprises europium(III) as an activator in a host lattice selected from the compounds of an anionic oxygen-containing species with a cationic metal species, comprising yttrium(III) and gadolinium(III). Furthermore the invention relates to the use of the phosphor for general illumination, traffic and signage lighting, automotive and for backlighting of liquid crystal displays.

    摘要: The invention relates to a display screen comprising a phosphor composition of a sulphide and/or selenide-containing phosphor which is provided with a coating which is composed of germanium disulphide and/or germanium diselenide. In such a display screen, in particular a low-energy cathode ray display screen, the advantages of the efficient sulphide or selenide-containing phosphors can be used and said display screen remains bright and rich in contrast for a long period of time because the coating, which is composed of germanium disulphide and/or germanium diselenide, surprisingly acts as a stabilizing protective coating which limits the corrosion processes in sulphide and/or selenide-containing phosphors induced by low-energy radiation.

    摘要: The luminescent phosphor degradation in a cathode ray display tube, caused by aging, is decreased. This decrease is achieved by introducing before and/or during evacuation a hydrolyzable gas into the tube's inner space for a limited time interval, using a partial pressure which is essentially larger than the eventual final vacuum pressure of the cathode ray tube, and then allowing the final vacuum pressure to be achieved without any further supply of gas. Thereafter, the cathode ray tube is sealed in a gastight manner.
