摘要： A body of cerium-doped quartz glass is manufactured by melting together silicon oxide and a cerium (III) silicate compound, preferably Ce.sub.2 Si.sub.2 O.sub.7, in a reducing atmosphere. The invention provides a method of manufacturing said cerium-silicate compound having a tetragonal crystal structure. The quartz glass manufactured can be suitably used in a lamp envelope of UV-absorbing quartz glass, the water content in the quartz glass being less than 1 ppm.

摘要： Magnesium fluoride layers are obtained by disproportionation of fluorine-containing organic magnesium compounds, notably magnesium trifluoroacetate, magnesium trifluoroacetylacetonate and magnesium hexafluoroacetylacetonate. A solution of such a compound is provided on the substrate in an organic solvent by spinning or dipping at room temperature after which the layer is heated to 500.degree. C. The solution may also be atomized and sprayed on the substrate which is maintained at a temperature of 600.degree. C. It is possible by means of this method to provide pure magnesium fluoride layers at a comparatively low temperature in air and without using film forming vehicles. The MgF.sub.2 layers obtained according to said method are useful as anti-reflective layers on display screens, on optical elements and as components in a multilayer packet, for example a dichroic mirror.

摘要： Metal-oxide layers having a high .delta..sub.max, such as in particular magnesium-oxide layers, are provided on a glass substrate, such as a selection plate or a channel plate, of an electronic display device by means of a spray-pyrolysis process. To this end, a solution of a metal salt, such as Mg acetate, in ethanol or another (organic) solvent and/or water is sprayed onto a substrate which is maintained at a temperature of 350-550.degree. C. In a display device which is provided with such a layer on the bottoms and walls of the channels of the channel plate, a minimum transport voltage of 50-100V/cm is required.

摘要： An electron-emitting surface is provided with a material reducing the electron work function, which is obtained from a suitable reaction. The reaction mixture or the product to be decomposed, for example CsN.sub.3, is present in a surface depression of a semiconductor body, while one or more pn junctions act as a heating diode. Upon heating, cesium is released and deposited on the electron-emitting surface.
