摘要：A mercury vapor discharge fluorescent lamp is provided having a phosphorlayer that has a yttria-based red emitting rare earth phosphor. The phosphor layer isprepared from an aqueous phosphor slurry that is coated onto the inner surface of theglass envelope of the lamp, then baked in a lehring oven to vaporize or decompose non-
phosphor components of the slurry to leave behind the finished phosphor layer. Thephosphor slurry contains a non-ionizing thickener, preferably polyethylene oxide, butdoes not contain any calcium carbonate or carbonate salts. The phosphor layer includes ayttria-based red emitting rare earth phosphor.
