Abstract

In this work we report a new carbon nanotubes field emission (CNT-FED) light source with nanocrystalline phosphors. The nanocrystalline powders of cerium doped yttrium aluminum garnet were obtained by modified Pechini method. The phosphor has been electrophoretically deposited on ITO-glass substrates. The cathode composed of carbon nanotubes was fabricated in the same manner. A light source was assembled and tested. Low-voltage cathodoluminescent spectra and I-V characteristics of fabricated cathodes were measured. A possibility of application of Ce doped nanocrystalline YAG phosphor in the field emission displays (FEDs) was discussed.
