Abstract

The invention discloses a field emission illumination device comprising a first substrate, a second substrate, a micro channel plate, a grid layer, a positive layer and a fluorescent layer. The micro channel plate is mounted between the first substrate and the second substrate; the grid layer is mounted between the first substrate and the micro channel plate and provided with a grapheme field emission assembly; the positive layer is mounted between the second substrate and the micro channel plate; and the fluorescent layer is mounted between the micro channel plate and the positive layer. With grapheme as an emission source, start voltage of the field can be reduced; and with the micro channel plate as an electronic multiplier pipe, when an electron passes through the micro channel plate, an axial electric field of the micro channel plate forces the electron to have a crash with the channel wall for a plurality of times, so electron numbers are multiplied.

Description

technical field [0001] The present invention relates to a field emission luminescent device and its method, in particular to a field emission luminescent device and its method which use graphene as a field emission source and increase current by means of a microchannel plate. Background technique [0002] The existing electron emission forms can be mainly divided into electron field emission (Electron field emission), thermionic emission (Electron thermionic emission), photoelectron emission (Photo electron emission) and secondary electron emission (Secondary electron emission), and the electron field emission The principle of launch is quite different from the other three. [0003] Among them, the principles of thermal electron emission, photoelectron emission and secondary electron emission all need to enable the internal electrons of the emitting object to obtain thermal energy, photon energy and secondary electron energy, so that they can obtain greater kinetic energy af...
