PROBLEM TO BE SOLVED: To provide a liquid for applying a phosphor in which discoloration of fluorescent film in a baking step of the phosphor is suppressed and uniformity of thickness of the fluorescent film in longitudinal direction of a fluorescent lamp can be ensured and to provide the fluorescent lamp having a stable luminescence property by using the liquid. SOLUTION: The liquid for applying the phosphor comprises water, a phosphor, a thickener and a binder and further, at least one compound selected from ammonium chloride, ammonium carbonate, ammonium hydrogencarbonate, ammonium hydrogencarbonate aluminate, ammonium fluoride, ammonium hydrogenfluoride, hydrazinium chloride, ammonium cyanate, ammonium nitrite, ammonium sulfite and ammonium acetate and the compound is included in an amount of≥0.05 g and≤4 g based on 1 kg phosphor. The fluorescent lamp is obtained by applying the fluorescent film 3 formed by the liquid for applying the phosphor to the inside of a glass tube 1. COPYRIGHT: (C)2005,JPO&NCIPI
