Embodiment 1
[0046] Carbon field emission electron emitters were prepared using the following method. A paste consisting of graphite particles and glass frit is screen-printed on a substrate and fired to form a composite layer comprising graphite particles and glass. This substrate consists of a layer of silver conductor composition on a glass plate.
[0047] A 22 mm x 22 mm layer of silver conductor composition (DuPont #7095 silver conductor composition, a screen printable The substrate was prepared from a thick film composition available from E.I. du Pont de Nemours and Company, Wiimington, DE), followed by firing at 525°C for 10 minutes to produce a conductive silver composite layer.
[0048] A paste consisting of graphite particles and glass frit was prepared by mixing 25% natural HPN-10 graphite powder, 25% glass, 37% vehicle, 10% beta terpineol, and 3% soy lecithin. The composition of the glass used is: 1.6% SiO 2 , 1.7% Al 2 o 3 , 85.8% PbO, 10.9% B 2 o 3 , the vehicle used c...
Embodiment 2
[0055] Use the method described in embodiment 1 to prepare carbonaceous field emission electron emitter basically, just the ion dose of incident is 10 19 ion / cm 2 .
[0056] When taken out of the vacuum chamber, the surface of the sample was examined using a scanning electron microscope, and the observed appearance consisted of a large number of larger pyramidal structures with a large base diameter and a very thin tip. The diameter of the base is about 3 microns, and the height of the structures is about 5 microns.
[0057] Electron emission from an ion-bombarded 1 cm x 1 cm area was obtained by placing a glass plate containing screen-printed and ion-bombarded graphite particles on the copper block of the measurement cell described above. Two pieces of conductive tape were applied to each side of the substrate to hold the substrate in place and provide electrical contact to the silver composite layer. The surface of the screen printed sample and the copper block anode were...
Embodiment 3
[0059] Two carbonaceous field emission electron emitters were prepared using essentially the method described in Example 1, with the following differences: .
[0060] (a) by screen printing a 22 mm x 22 mm layer of silver conductor composition (DuPont #7095 silver conductor composition, a A thick film composition, available from E.I. du Pont de Nemours and Company, Wiimington, DE), was screen printable to prepare a substrate for one emitter. A 7.75 inch by 7.75 inch (19.7 cm by 19.7 cm) layer of the same silver conductor composition was screen printed on an 8 inch by 8 inch (20.3 cm by 20.3 cm) glass plate for the second emission. Body substrate;
[0061] (b) For smaller samples, the paste was applied to the silver composite layer on the glass plate in a 14 mm x 14 mm square pattern as described in Example 1. For larger samples, the paste was applied to the silver composite layer on the glass plate in a square pattern 6.75 inches by 6.75 inches (17.1 cm by 17.1 cm);
