Abstract (en)
Glass discoloration by high energy electrons is avoided by applying a thin oxide layer on the surface of the glass that would otherwise be impacted by electrons, which is alkali-free, contains no ions inherently reducible by electron bombardment, and has a thickness larger than the depth of penetration of the electron beam at a given acceleration potential but insufficient color to interfere with desired color coordinate specifications. Suitable thin oxide layers comprise ZnO, SnO2, In2O3 and tin-doped indium oxide. <IMAGE>
