Abstract
We prepared chemical compounds whose Ce 3+ ions are replaced with Bi 3 + ions at a certain rate in LiCeMo 2 O 8 , NaCeMo 2 O 8 , Ca 0.5 CeMo 2 O 8 , and Sr 0.5 CeMo 2 O 8 that have the sheelite crystal structure, and the change of the hue of these materials was investigated. In addition, the cause of Ce 3+ ion color development in the sheelite structure was studied based on the result of substituting Bi 3+ ions for Ce 3+ ions and change of the hue of the compounds whose Mo 6+ ions are replaced with W 6+ ions. The result revealed that the absorption edge shifted to the longer wavelength side as the amount of the replaced Bi 3 + ions increased, and the hue of the product changed from yellow to reddish yellow. The changes in the chemical bonding nature of the crystal were found to give a great impact on the color development of the Ce 3+ ion. Although the Ce 3+ ion takes on the yellow hue in the sheelite crystal structure, its absorption edge can be shifted freely by generating the substitutional solid solution of metal ions with different electronegativity.
