Abstract
The invention relates to non-aqueous suspensions for the deposition of luminescent materials, particularly phosphors by electrophoresis. These suspensions comprise an organic, polar solvent constituted by a mixture of nitromethane and an aliphatic alcohol such as isopropyl alcohol, containing in solution at least one metal salt and at least one vegetable protein, as well as a powder of the luminescent material to be deposited in suspension in said solvent. These suspensions can be used for the production of tricolour screens having conductor tracks (15, 16, 17) covered with first colour (18), a second colour (19) and a third colour (20), the excitation of the phosphors being carried out by means of an electron source (1) having an emissive cathode with microtips (1c).
