Field emission properties of carbon nanotube cathodes produced using composite plating
Source abstract
Abstract
Field emission properties of carbon nanotube field emission cathodes (CNT-FECs) produced using com- posite plating are studied. The experiment uses a CNT suspension and electroless Ni plating bath to carry out composite plating. The CNTs were first purified by an acid solution, dispersed in a Ni electrobath, and finally co-deposited with Ni on glass substrates to synthesize electrically conductive films. Field emission scanning electron microscopy and Raman spectroscopy results show that the field emission characteris- tics and graphitic properties of CNT-FECs depend on the pH value of the electrobath. Experiments show that the optimum electrobath pH value is 5.4, achieving a field emission current density of 1.0 mA/cm2 at an applied electric field of 1.5 V/m. The proposed CNT-FECs possess good field emission characteristics and have potential for backlight unit application in liquid crystal displays.
