Abstract
Luminescent materials are adhered to TV color picture screens or image display device screens by coating the inner surface of a glass screen substrate with a conductive or non-conductive C.sub.1 to C.sub.4 alcoholic or carboxylic solution containing oxygen-rich organic materials selected from the group consisting of silicon salts of relative low molecular weight carboxylic acids, tin salts of relatively low molecular weight carboxylic acids (which can be optionally doped to render them conductive, if desired) or mixtures thereof or a doped tin compound, at least partially drying such coating, as at a temperature of about 150.degree. C., applying a select pattern of luminescent materials onto such partially dried coating and curing or tempering the resultant structure, as at a temperature of about 500.degree. C. so that the luminescent material is firmly embedded within the conductive/non-conductive coating.
