Gradient light-absorbing SiOx/Me coatings for display panels

Thin (<0.5 mum) gradient SiOx/Ti coatings with a low coefficient of specular reflection (less than or equal to1%) in the visible part of the spectrum are obtained by thermal evaporation in vacuo. The optical parameters and the distribution of the components across the coating are studied. The optical properties of the gradient layers are simulated, and the results of simulation are compared with experimental data. These coatings can be used in fabricating black (light-absorbing) matrices for cathode-ray tubes and flat-panel displays. (C) 2002 MAIK "Nauka / Interperiodica".
