Abstract: We studied new preparation conditions for scallop shell phosphors to suppress weathering and the disappearance of fluorescence, and measured the fluorescence properties of these phosphors. When a shell was fired to 900°C in a carbon dioxide atmosphere, weathering and the disappearance of fluorescence could be suppressed. It was found that the higher brightness of the shell phosphor fired at 860°C was about 6cd/m2, when the power of irradiated UV light was about 1.6 W/m2. The emission spectrum shows three bands, with peaks at about 420 nm, 485 nm and 585 nm. The bands at 420 nm and 485 nm are presumed to be due to Cu, and the band at 585 nm is presumed to be due to Mn.
