Abstract:

Suitable colloidal suspensions for depositing P-15, P-16, P-24 phosphors electrophoretically were developed. Phosphor screens with resolutions exceeding 80 line pairs per millimeter were deposited cataphoretically on glass using intermediate zinc and magnesium coatings which were subsequently removed by physical or chemical means. Stable P-24 suspensions were developed which can be elutriated for over 80 hours. Chemical composition and spectral emission characteristics of the electrically deposited phosphors were found to be similar to the starting material indicating no changes were caused by the deposition process. Qualitative spectrometer and quantitative efficiency measurements indicate an increase in radiant efficiency for cataphoretic P-16 screens under electron excitation at low current densities. Electrical measurements also indicate that the mechanism of emission from cataphoretic P-16 screens is different from settled P-16 screens and other cataphoretic screens such as P-15 and P-24.
