摘要：
According to the present invention, there is provided a method for forming a color tube phosphor screen comprising the steps of forming a light-absorbing matrix having holes on a faceplate, coating a silica colloidal solution or an alumina colloidal solution containing a multivalent metal ion in said holes and washing said holes, and forming phosphor layers of three colors in said washed holes. The color tube phosphor screen formed through the method of present invention has no phosphor residual, especially pigment residual.
