The phosphors of Y2O3:Eu3+,Tb3+, ZnS:Cu+,Al3+ and ZnS:Ag+,Al3+,Cl- have been used in field emission display (FED) as red, green and blue phosphors, respectively. In this study, the phosphors (R, G, B) were coated by In2O3, using a sol-gel method to improve luminescence efficiency, resistance to current saturation and chemical stability. The coating effect on the cathodoluminescence (CL) properties was investigated as a function of applied voltage. For the ZnS:Cu+,Al3+ and ZnS:Ag+,Al3+,Cl- phorsphors coated with more than 10 wt% In2O3, the CL aging was markedly improved at voltages higher than 10 keV. For the Y2O3:Eu3+,Tb3+ phosphor, the coating of In2O3 nanoparticles was found to be very effective in the improvement of the cathodoluminescence efficiency. For the 7 wt% In2O3-coated red phosphor, the CL intensity was increased more than 10 %, compared with that of the uncoated phosphor at voltages higher than 13 keV.
