ABSTRACT:
A process for manufacturing a conductive and light-absorbing baseplate for use in a field emission display is disclosed. A surface of the baseplate is coated with a praseodymium oxide- and manganese oxide-containing layer having a resistivity that does not exceed 1.times.10.sup.5 .OMEGA.-cm. The coating may be placed on the baseplate by radiofrequency sputtering, laser ablation, plasma deposition or the like. Suitable praseodymium sources include praseodymium acetate, praseodymium oxalate and Pr(THd).sub.3, while suitable manganese sources include MnO.sub.2 and MnCO.sub.3.
