Abstract
Particles of electroluminescent phosphor having a moisture proof coating are re-coated by treating the phosphor in a fluidized bed with a mixture of water vapor and an organotrichlorosilane compound for approximately thirty minutes. The resultant siloxane coating further improves the moisture resistance of the phosphor.
