Abstract
PURPOSE:To stabilize the viscosity of a phosphor slurry by adding a surfactant which suppresses the gelation of polyvinyl alcohol to the phosphor slurry. CONSTITUTION:A red phosphor, (Zn,Mg)3, (PO4)2: Mn, is suspended with polyvinyl alcohol, a dichromate and water, thereby a phosphor slurry being prepared. After that, the phosphor slurry is added with a surfactant, such as sodium naphthalene sulfonate, which is a formalin condensate of naphthalene sulfonate, sodium lignin sulfonate, which is a lignin sulfonate, or sodium riboflavin phosphate, which is a phosphate, so as to prevent the gelation of the said polyvinyl alcohol. Consequently, the viscosity of the phosphor slurry can be stabilized for a long period of time.
