Abstract
The phosphors used in conventional cathode ray tubes (CRTs) are difficult to use at voltages lower than 500 V, because of charge buildup on their surface. To overcome this drawback a ZnS:Ag,Cl phosphor was coated with a very thin In2O3 conductive layer by the sol-gel method using tri-iso-propoxyindium. Properties of the cathodoluminescence at voltages ranging from 50–500 V were studied and compared with those of the as-received ZnS:Ag,Cl phosphor. It was found that the luminance of the In2O3-coated phosphor was far better than that of the as-received phosphor when they were excited using an electron beam with an energy of less than 500 eV. Furthermore, the aging characteristics of the cathodoluminescence showed marked improvement.Keywords
