Cathodoluminescence from a device of carbon nanotube-field emission display with ZnO nanocluster phosphor

Journal Article · · Nanotechnology, 18(29):295703

Carbon nanotube (CNT) cathodes are electron emitters that operate at room temperature, which are a suitable replacement for thermionic emitters. Cathodoluminescence (CL) is measured for the first time with ZnO nanoclusters as a phosphor for a CNT-FED (carbon nanotube-field emission display) device. The CNT cathode is operated in diode mode with beam currents of 10 and 20 mA and low accelerating voltages of 1.7 and 1.8 kV. CL exhibits two peaks: the first peak in the visible range with a broad full width half-maximum (FWHM) and a much narrower second peak (384 nm) in the ultraviolet (UV) range.
