It is well-known that the phosphor is widely used for the field emission display (FED)
and its luminescent and temperature properties are very important for the effect of display. In this paper
we propose a measurement scheme for the phosphor
and design a test-equipment to test the luminescent and temperature properties of phosphor. Furthermore
the equipment can also be used for the life-test of the phosphor because it can generate a great excitation power. Finally
there are design principle
structure and some data and result which we obtained in the experiment. These data will be very useful for the design of FED. (2010) Trans Tech Publications.

Carbon nanomaterials have attracted considerable attention and interest owing to the unique physical and chemical properties. Such as nanodiamonds
carbon nanofibers
carbon nanotubes (CNTs)
graphene and so on
they all have potential applications as field electron emission materials
electrode materials
storage hydrogen materials and composite materials. In this paper we reported the growth of layered graphene(LG) on carbon fibers surface. The LG synthesized on carbon fibers may have potential applications in many fields. For example
using to improve the electric conductivity and chemical stability of carbon fibers substrate
the grown LG can be applied as high performance capacitor
battery
field emission electron source
hydrogen storage owing to large ratio surface and hybrid multiscale composite. 2010 IEEE.

Since CVD diamond film possesses desirable properties
it has been widely investigated
and much research has been made in this field. In this experiment
we mainly studied the characteristics of field emission from the CVD diamond films. The motivation for the experiment is to gain some insight into a possible emission mechanism. The diamond films are grown using a hot filament chemical vapor deposition
basing on the diamond micro-grits on silicon substrates. And the diamond micro-grits are deposited on silicon substrates using electrophoresis coat method
through a solution of diamond micro-grits in ethyl alcohol. This study has revealed that emission can be obtained at fields as low as 1.8V/m. And the field emission measurements were carried out at a pressure of 10-4Pa.

Carbon nanotubes were dispersed in isopropyl alcohol solution which containing 210-5 mol/L dissolved Mg(NO3) 2·6H2O. The nanotubes were deposited on the conducting substrates as field emitters with electrophoretic deposition method. Some carbon nanotubes film specimens with different thickness were obtained by adjusting the deposition time. The field emission properties have been tested with a diode structure below 110-4 Pa. CNTs film deposition thickness around 1.4 m showed higher field emission current. During the electrophoretic deposition process
the magnesium hydroxide formatted too. The metal hydroxide existing in the carbon nanotube film and on the substrates
would affect on the field emission properties evidently. 2006 IEEE.

Carbon nanotubes have been attracting attention because of their unique physical properties and their application potential for field emission cathode. Carbon nanotubes possess the following properties favorable for field emission material
such as a high aspect ratio and sharp tip
high chemical stability
high mechanical strength
stable at high temperature. Some research works on carbon nanotubes field emitter and field emission display have been reported. Here
a kind of carbon microtubes and its field emission properties are introduced. They have some different properties with carbon nanotubes
and the density is lower than carbon nanotubes bundles. These carbon microtubes are directly synthesized by liquidoid epitaxy method on silicon substrates at low temperature. The field emission properties of carbon microtubes are reported too. Carbon microtubes film is synthesized in liquid by electrolysis. The graphite plate is as anode
and n-silicon substrate with resistivity of 4-8 cm is as cathode. The electrolysis current is about 5-8mA/cm2
and applied voltage is 800-1500V. Temperatures of the methanol base solution is maintained at 60C in process of deposition of carbon microtubes. Carbon microtubes film is observed by scanning electron microscopy(SEM)
as shown in fig.1(a
b). The wall's thickness of carbon microtube is about 60nm. The diameter of carbon microtube is about 0.8 m. Raman spectrum of carbon microtubes film shows the two peaks at 1342and 1560cm-1. The field emission properties of carbon microtubes are measured in high vacuum chamber(10-5Pa). The emission area of carbon microtubes is 0.5cm 0.5cm. The threshold of field emission of the carbon microtubes film is about 3.6V/ m. Field emission property of carbon microtubes film is shown in fig.2. Another
when the electric field between anode and cathode is 10V/ m
the electric field distribution on single carbon microtube is also given after calculation according to electric field theory. Fig 3 shows that electric field distribution vertical section on the of single carbon microtube top with 2 m of highness. These results may help us to understand field emission properties of carbon microtubes. According to research results
it is found that liquidoid synthesis is simple method to produce carbon microtubes cold cathode material
and the carbon microtubes have better field emission properties. 2005 IEEE.

Patterned carbon nanotubes on silicon substrates were obtained using electrophoretic method. The carbon nanotubes migrated towards the patterned silicon electrode in the electrophoresis suspension under the applied voltage. The carbon nanotubes arrays adhered well on the silicon substrates. The surface images of carbon nanotubes were observed by scanning electron microscopy. The field emission properties of the patterned carbon nanotubes were tested in a diode structure under a vacuum pressure below 5 10-4 Pa. The measured emission area was about 1.0 mm2. The emission current density up to 30 mA/cm2 at an electric field of 8 V/m has been obtained. The deposition of patterned carbon nanotubes by electrophoresis is an alternative method to prepare field emission arrays. 2005 Elsevier B.V. All rights reserved.
